GCSE Physics Tutorial: Properties of Parallel Circuits
A parallel circuit is an electrical circuit where components are connected side by side, each having both its positive and negative terminals connected together. Understanding the properties of parallel circuits is essential in analyzing and designing electronic circuits. In this tutorial, we will recall the key properties of parallel circuits.
1. Current (I):
In a parallel circuit, the total current ($I_total$) is the sum of the currents flowing through each individual component (I₁, I₂, I₃, ...).
Each component in a parallel circuit has its own path for current to flow, resulting in the division of current among the components.
2. Voltage (V):
The voltage (potential difference) across each component in a parallel circuit is the same.
Each component receives the full voltage from the power source, and the voltage across each component is equal to the total voltage (V_total) across the parallel circuit.
3. Resistance (R):
The total resistance (R_total) in a parallel circuit is calculated using the formula:
1/$R_{ \text{total}}$ = 1/R₁ + 1/R₂ + 1/R₃ + ...
4. Brightness of Bulbs (Lamps):
In a parallel circuit with multiple light bulbs (lamps), each bulb shines at its full brightness, regardless of the number of bulbs connected.
The reason is that each bulb has its own path for current, and they all receive the full voltage, resulting in independent operation.
5. Circuit Reliability:
In a parallel circuit, if one component fails or is disconnected, the other components remain unaffected and continue to function.
This property makes parallel circuits more reliable than series circuits for certain applications.
6. Key Points:
In a parallel circuit, the total current is the sum of individual currents through each component.
Each component receives the same voltage as the total voltage across the circuit.
The total resistance is calculated differently from series circuits, using the reciprocal sum of individual resistances.
Bulbs connected in parallel shine at their full brightness independently.
Applications of Parallel Circuits:
Parallel circuits are widely used in household electrical wiring, battery-powered devices, appliances, and electronic devices where each component requires the same voltage but different currents.
Parallel connections are also used in electrical power distribution, where multiple loads are connected to the same power source independently.
Summary: In a parallel circuit, the total current is the sum of individual currents, and the voltage across each component is the same. The total resistance is calculated using a different formula from series circuits. Understanding the properties of parallel circuits is essential in circuit analysis and designing electrical systems for various electronic applications.

In circuits with resistors connected in series, calculating the total resistance can become tedious when dealing with multiple resistors. However, the concept of equivalent resistance simplifies these calculations by combining the individual resistors into a single equivalent resistor. This tutorial will guide you through solving problems for circuits with resistors in series using the concept of equivalent resistance.
1. Understanding Series Circuits: In a series circuit, resistors are connected one after the other, forming a single path for current flow. The key property of series circuits is that the current remains constant throughout the circuit since it experiences the same resistance in each resistor.
2. Equivalent Resistance (R_eq): Equivalent resistance is a single resistance that represents the total opposition to current flow in a series circuit. When resistors are connected in series, the equivalent resistance (R_eq) is the sum of all individual resistances.
For two resistors (R₁ and R₂) in series:
R_eq = R₁ + R₂For three resistors (R₁, R₂, and R₃) in series:
R_eq = R₁ + R₂ + R₃And so on for any number of resistors in series.
3. Steps to Solve Problems: Follow these steps to solve problems for circuits with resistors in series using the concept of equivalent resistance:
Step 1: Identify the Resistors in Series:
Examine the circuit diagram and identify the resistors connected in series. Resistors in series have their terminal ends connected to each other.
Step 2: Calculate the Equivalent Resistance (R_eq):
Add up the resistances of all the resistors in series to find the equivalent resistance:
R_eq = R₁ + R₂ + R₃ + ...
Step 3: Apply Ohm's Law:
If the circuit has a power supply (battery or voltage source) and you are given the potential difference (voltage) across the circuit, use Ohm's law to calculate the current (I):
I = V / R_eq
Step 4: Analyse the Circuit:
Use the calculated equivalent resistance and current to analyse the circuit further. For example, you can determine voltage drops across individual resistors, power dissipation, or total circuit current.
4. Example Problem: Consider the following series circuit with three resistors:
[Power Supply] --- [R₁] --- [R₂] --- [R₃] --- [Negative Terminal]Given: R₁ = 5 Ω, R₂ = 10 Ω, R₃ = 8 Ω, V (potential difference) = 12 V
Solution:
Calculate the equivalent resistance (R_eq):
R_eq = R₁ + R₂ + R₃
R_eq = 5 Ω + 10 Ω + 8 Ω
R_eq = 23 ΩCalculate the current (I) using Ohm's law:
I = V / R_eq
I = 12 V / 23 Ω
I ≈ 0.52 A (Amperes)5. Practical Applications:
The concept of equivalent resistance is invaluable in simplifying circuit calculations and analysing the behaviour of circuits with multiple resistors in series.
It is commonly used in electronics, household electrical circuits, and electrical engineering applications.
6. Summary: Solving problems for circuits with resistors in series becomes more manageable using the concept of equivalent resistance.

GCSE Physics Tutorial: Calculating Current, Potential Difference (Voltage), and Resistance in DC Circuits
In DC (Direct Current) circuits, calculating current, potential difference (voltage), and resistance is essential in understanding circuit behaviour and designing electronic systems. This tutorial will guide you through the process of calculating these quantities in DC circuits.
1. Current (I) Calculation: Current (I) is the rate of flow of electric charge through a circuit. It is measured in amperes (A). To calculate current in a DC circuit, use Ohm's law:
I = V / RWhere:
I = Current (in amperes, A)
V = Potential Difference (Voltage, in volts, V)
R = Resistance (in ohms, Ω)
2. Potential Difference (V) Calculation: Potential Difference (V), also known as voltage, represents the electric potential energy difference between two points in a circuit. To calculate potential difference in a DC circuit, rearrange Ohm's law:
V = I * RWhere:
V = Potential Difference (in volts, V)
I = Current (in amperes, A)
R = Resistance (in ohms, Ω)
3. Resistance (R) Calculation: Resistance (R) is a property that opposes the flow of current through a circuit. It is measured in ohms (Ω). To calculate resistance in a DC circuit, rearrange Ohm's law:

V = Potential Difference (Voltage, in volts, V)
I = Current (in amperes, A)
4. Example Calculations: Let's go through a couple of example calculations:
Example 1: Calculate the current flowing through a resistor with a resistance of 20 Ω when the potential difference across it is 10 V.
I = V / R
I = 10 V / 20 Ω
I = 0.5 A (Amperes)Example 2: Calculate the potential difference across a resistor with a resistance of 100 Ω when the current passing through it is 0.2 A.
V = I * R
V = 0.2 A * 100 Ω
V = 20 V (Volts)Example 3: Calculate the resistance of a resistor when the potential difference across it is 12 V and the current flowing through it is 0.5 A.
R = V / I
R = 12 V / 0.5 A
R = 24 Ω (Ohms)5. Practical Applications:
Calculating current, potential difference, and resistance is essential in designing and analysing electronic circuits, household wiring, and electronic devices.
These calculations are crucial for troubleshooting circuits and understanding component behaviour in real-world applications.
6. Summary: In DC circuits, current, potential difference (voltage), and resistance are interrelated through Ohm's law.

2. Circuit Layout: The DC series circuit is constructed by connecting the components in a sequential manner, one after the other, to form a single loop for current to flow through. The positive terminal of the power supply is connected to one end of the first resistor, and the negative terminal is connected to the other end of the last resistor. The ammeter and voltmeter are inserted at specific points to measure current and voltage, respectively.
3. Step-by-Step Setup: Follow these steps to set up a DC series circuit for measuring and testing:
Step 1: Power Supply Connection
Connect the positive terminal of the power supply to one end of the first resistor.
Connect the negative terminal of the power supply to the other end of the last resistor.
Step 2: Resistor Connections
Connect the resistors in series by connecting the free end of one resistor to the other resistor's free end, and continue until all resistors are connected in sequence.
Step 3: Ammeter Placement
Insert the ammeter in series with the resistors. This means connecting the ammeter in line with the current flow, typically by disconnecting one of the resistor connections and inserting the ammeter between the gap.
Step 4: Voltmeter Placement
To measure the voltage across a specific resistor, insert the voltmeter in parallel with that resistor. This means connecting the voltmeter across the resistor, connecting its positive lead to one end of the resistor and the negative lead to the other end.

GCSE Physics Tutorial: Qualitative Explanation of Series and Parallel Resistance
The total resistance in an electrical circuit changes when resistors are added either in series or in parallel. Understanding why adding resistors in series increases the total resistance while adding resistors in parallel decreases the total resistance, is essential in circuit analysis. In this tutorial, we will provide a qualitative explanation for these changes.
1. Resistors in Series: When resistors are connected in series, they are placed one after the other, forming a single path for current to flow through. The current passing through each resistor is the same because there is no branching of the current path. The key points to note are:
Resistance Addition: In a series circuit, the total resistance increases as more resistors are added. This is because the total resistance is the sum of the individual resistances of all the resistors in series.
Limited Current Flow: With resistors in series, each resistor restricts the current flow, making it more difficult for the current to pass through the circuit. As a result, the total resistance is higher compared to a single resistor.
2. Resistors in Parallel: When resistors are connected in parallel, they are placed side by side, each having both its positive and negative terminals connected together. Each resistor has its own path for current to flow through. The key points to note are:
Resistance Division: In a parallel circuit, the total resistance decreases as more resistors are added in parallel. This is because the total resistance is calculated differently for resistors in parallel compared to series.
Increased Current Flow: With resistors in parallel, the current is divided among the branches, which provides additional paths for current to flow. As a result, the overall resistance is reduced compared to a single resistor.
3. Intuitive Understanding: Think of resistors in series as a narrow pathway that restricts the flow of water (current). Each resistor adds more obstacles, making it harder for the water to flow smoothly, increasing the overall resistance.
On the other hand, consider resistors in parallel as multiple streams of water flowing independently side by side. Each stream has less restriction, and the total flow of water (current) increases, resulting in decreased resistance.
4. Formula for Total Resistance:
Resistors in Series: The total resistance (R_total) in a series circuit is the sum of the individual resistances (R₁, R₂, R₃, ...) of each resistor:
R_total = R₁ + R₂ + R₃ + ...Resistors in Parallel: The total resistance (R_total) in a parallel circuit is calculated using the formula:
1/R_total = 1/R₁ + 1/R₂ + 1/R₃ + ...
5. Summary: In summary, adding resistors in series increases the total resistance because they restrict the current flow, while adding resistors in parallel decreases the total resistance due to the division of current among the parallel branches. Understanding these qualitative explanations will help you analyse circuits with multiple resistors and design circuits with the desired resistance values for specific applications.
