Question

Write two points of difference between electric energy and electric power.

Answer 1

Hint: In this question we have been asked to differentiate between electric power and electric energy. Therefore, to answer this question, we shall first discuss what is electric power and electric energy. While doing so, we shall discuss the factors that make the two parameters different. We know that electric energy is derived from electric potential or kinetic energy.

Complete step-by-step answer:
Electric energy is usually defined as the energy that has been converted from electric potential. The energy that is generated due to the movement of charge carriers in a conductor is also known as electric energy.
Electric power is the rate at which electric energy is consumed by an electric circuit. It is also known as the rate at which work is done in the electric system. Electric power is given as the ratio of electric energy per unit time.
Therefore, electric energy is generation energy in a system and electric power is the rate of consumption of this generated energy. The SI unit of energy is Joules and that of electric power is Watts. Electric energy determines the amount of electric work done and electric power determines the rate of work done.

Note: Electric energy is the energy generated from the movement of the electrons from one end to another. The movement of charged particles in conductors generates electricity. The electric energy can be converted into other types of energy such as heat energy or mechanical energy. The fan is an example of electric energy being converted into mechanical energy.
