 # Difference between Electric Energy and Electric Power | with Calculator

In this post, we are going to learn about the difference between electric energy and electric power.

Both are the crucial terms that you might have heard in an electrical and electronics circuit.

Many of us think both Electrical Energy and Electrical Power are same. But, both are different.

#### Difference between Electric Energy and Electric Power

Here, I am comparing in between the electrical energy and electrical power in tubular form.

#### Explanation of Electrical Energy and Electrical Power

What is the relation between electrical energy and power?

Here, I am describing simple explanation about the energy and power relation.

Suppose, a DC voltage source is connected through the battery to an electric circuit.

The main function of a battery is to convert chemical energy into electrical energy. And it is able to store electrical energy or electricity.

This electrical energy helps to move electric charge (Q) particles or electric current through a conductor. The electric current always flows from the positive terminal to the negative terminal.

Hence, we can conclude that, energy has the capacity to transfer the charged particle from one place to another.

And power is to measure ‘how to transfer the energy with respect to time?’. So, the basic definition of power is ‘the rate of energy converts or transfer per unit time’.

For example, when we glow 100 W light bulbs for 60 Sec. How much energy would you use?

According to the above formula, electrical energy is calculated as…

`Electrical Energy, (W)=  (Power*Time)= (100*60)= 6000 Joule`

So, here we require 600 joule energy for 100 watt bulb.

#### Calculation of Electrical Energy and Electrical Power

Electrical Energy Calculation:

From Current, Voltage and Time:

From Power and Time:

Electrical Power Calculation:

From work done and time:

From Energy and Time:

Thus, in this post, I have explained the difference between electric energy and electric power.
