Physics 2013 JAMB Past Questions - Question 42: When a charge moves through an electric circuit in the direction of an electric force ,it

Correct Answer

C

Explanation

Achargegains kinetic energy when it moves in the direction of an electric field.Moving charges create magnetic fields which deflects the electron, therebyreducing the potential energy. The principle of conservation of energy aisoholds at atomic level.
experiences a transfer of energy. This transfer of energy is due to the work done by the electric force on the charge. As the charge moves through the circuit, it encounters various components such as resistors, capacitors, and inductors. These components can either impede or facilitate the flow of charge, depending on their properties.

In the case of resistors, they impede the flow of charge by converting some of the electrical energy into heat. This is known as electrical resistance. As the charge passes through a resistor, it loses some of its energy in the form of heat, and the resistor gets warm.

On the other hand, capacitors and inductors store energy in an electric or magnetic field, respectively. When a charge moves through a circuit containing capacitors or inductors, it can transfer energy to these components, which then store it. This stored energy can be released back into the circuit at a later time.

Overall, as the charge moves through the circuit, it experiences a transfer of energy due to the work done by the electric force and interactions with various circuit components.
