Question

How are electric power and electric energy related?

Answer 1

Hint: In this question we have to explain the relation between electric power and electric energy. For this we will first understand what electric power and electric energy are then we will understand the relation between these two.

Complete step by step answer:
Electrical Energy - electrical energy is a kind of energy that we get from the energy of charged particles. Electrical energy can be defined in this way that when an electron moves from one point to another it generates electrical energy. The movement of charged particles through the medium gives rise to electrical current. Unit of electrical energy is Joule. Formula to find electric energy is given below,
E=QV
Where,
E is electric energy in joule
V is potential difference in volts
Q is electric charge in coulomb
Electric Power – Electrical power is the rate at which work is being done or energy is being transformed into an electrical circuit. We can define electrical power in this way that electrical power is a measure of electrical energy used in an interval of time. Unit of electrical power is Watt. Formula to find electric power is given below,
P=VI
Where,
P is electric power Watt
V is potential difference in volts
I is current in ampere
Hence, from the above explanation we can see that electric power is the rate of change of electrical energy. So this is how electric power and electric energy are related to each other.
Result- Hence, from the above explanation we can clearly understand how electrical power and electrical energy are related to each other.

Note:
Electric power and electrical energy both have a big significance in the electrical field. To know how much energy is being generated and how much energy is being used in any electrical circuit we require knowledge of electric power and electric energy.
