GCSE Physics Tutorial - Electrical Field Pattern of an Isolated Charged Sphere
In this tutorial, we will explore the electrical field pattern generated by an isolated charged sphere. The electric field around a charged object, like a sphere, is crucial in understanding how electric charges interact with other objects in their vicinity. We will learn how to draw the electric field lines and understand their significance.
Electric Field Lines and Their Representation: Electric field lines are a visual representation of the electric field surrounding a charged object. These lines show the direction and intensity of the electric field at different points around the charged sphere. Electric field lines always point away from positively charged objects and toward negatively charged objects.
Electrical Field Pattern of an Isolated Charged Sphere: For an isolated charged sphere, the electric field lines are radially symmetric, emanating from the center of the sphere and extending outward in all directions. The field lines appear as continuous lines that do not intersect or cross each other.
Key Features of the Electric Field Pattern: a. Density of Field Lines: The density of electric field lines represents the strength of the electric field. The closer the field lines are to each other, the stronger the electric field in that region. Similarly, the farther apart the lines, the weaker the electric field.
b. Equally Spaced Field Lines: For an isolated charged sphere, the electric field lines are equally spaced from each other. This symmetry ensures that the electric field strength is the same at equal distances from the center of the sphere.
c. Radial Direction: All electric field lines radiate outward from the center of the sphere in a radial direction. This indicates that the electric field is directed away from the positively charged sphere.
Drawing the Electric Field Pattern: To draw the electric field pattern of an isolated charged sphere:
Step 1: Identify the Charge: Determine whether the sphere is positively or negatively charged. Remember, electric field lines point away from positive charges and toward negative charges.
Step 2: Start at the Center: Begin drawing the electric field lines at the center of the sphere, as this is the source of the electric field.
Step 3: Radial Outward Lines: Draw lines that extend radially outward from the center of the sphere. These lines should be equally spaced and show the direction of the electric field away from the charged sphere.
Step 4: Complete the Pattern: Continue drawing the field lines until they cover the entire space around the charged sphere. Remember that they should not intersect or cross each other.
In this tutorial, we have learned how to draw the electrical field pattern for an isolated charged sphere. The radially symmetric pattern with equally spaced field lines emanating from the center of the sphere demonstrates the electric field's behaviour in the space around the charged object. Understanding electric field patterns is essential in comprehending the behaviour of electric charges and their interactions with other objects.
