# What is the electrical energy definition formula? Unit of electrical energy.

**What is electrical energy?**

Before explaining what electrical energy is, consider the potential difference between two points of an electric field.

**Learn to pronounce**

**Suppose the potential difference between point A and point B in an electrical unit is equal to V volts.**

**Learn to pronounce**

**According to the definition of the potential difference, it can be said that when a positive electric charge unit, which is a body containing a positive charge to a coulomb, moves from point A to point B, it will operate V joules.**

**When the Coulomb charge moves from point A to B, it will operate in joules instead of a Coulomb charge.**

**If the time required for the charge q Coulomb to move from point A to point B is equal to t second, we can write the working rate as follows:**

Again, we define the work done per second as a force. In this case the term

would be the electric current. In differential form one can write electrical energy

Watt is the power adapter.

Now if we place a conductor between A and B through which the amount of electric charge q Coulomb flows. The load flowing through a cross section of the conductor per unit of time (second) is

This is nothing but the electrical current i through the conductor.

Now we can write

If this current flows through the conductor for a time t, we can say that it is the total work done by the load

*e = vit joules*

We define this as electrical energy. So we can say

Definition of electrical energy

Electrical energy is work done by electrical charge. When the current i ampere flows through a conductor or other conducting element with a potential difference v volts for a time t seconds, the electrical energy is:

*e = vit joules*

Formula for electrical energy

The expression of electrical energy is

**P = vi watts**

Electric energy is

*e = vit joules*

Unit of electrical energy

Basically, we find that the unit of electrical energy is Joule. This corresponds to one watt x one second. In the trade, we also use other electrical energy units such as watt-hours, kilowatt hours, megawatt hours and so on.

Watt hour

When one watt of energy is consumed for 1 hour, the energy consumption is one watt-hour.

BOT unit or Chamber of Commerce or Kwh

The kilowatt hour is a practical and commercial unit for electrical energy. The base business is the watt-hour and one kilowatt-hour means 1,000 watt-hours. Electric utilities calculate the power consumption per kilowatt-hour. This kilowatt hour is the unit of the Chamber of Commerce, which is a BOT unit.
