Electrical energy is a form of energy resulting from the flow of electric charge. Energy is the ability to function, where no force works on carrying an object. We need to use energy every day and energy is available in all different forms, Electric energy can be either potential energy or kinetic energy, but it usually comes in the form of potential energy. Electrical energy is the energy that is stored in charged particles within an electric field. Electric fields are just areas surrounding a charged particle. In other words, charged particles from electric fields which put emphasis on other charged particles within the region. The electric field forces the charged particle, which makes it move – in other words, to work. If sufficient charge is made, then the electricity can be discharged to make a spark (or even electricity), which has electrical kinetic energy.

Unit of Electric Energy

Actually, we find that the unit of electrical energy is joule. This one-watt x is equal to one second. We also use other units of electrical energy, such as watt-hours, Kilowatt-hours, and megawatt-hours more.

What Are Electric Fields?

To understand the electrical energy, let’s learn a little bit about the electric field. The electric fields are like gravitational fields, both of which are surrounded by objects affected by the area object.

A gravitational field surrounds the Earth, which gives us a power that can pull us down. Similarly, the electric field is charged around the force of particles and the force of charged particles in the area. Have you ever heard the expression ‘attracting opponents’? It certainly applies to the electric field.

The direction of the electric field is always directed away from a positive source charges to negative sources charges

The image above shows the surrounding electric field both positive and negative sources. The arrow you saw indicates that a positive test charge will take place in the area. Positive objects make electric fields that suppress other positive things; thus, arrows are directed away from positive sources. Negative sources create electric fields that attract positive objects; therefore, the arrows you watch are directed towards the negative source. It is important to remember that the direction of the electric field always indicates that a positive particle will be transferred to that area.

Formula ofElectric Energy.

The formula that links energy and power is:

Power = Volt x Current

P = E x I

Energy = Power x Time

J = W x T

Note: The unit of energy is joule, the unit of power is the watt, and the unit of time is second.

E.g. If the bulb 100 of watts is turned on for an hour, then how many joules of electrical energy have been converted by the lamp?

J = W x T

= 100 x 3600

= 360000 joules

Examples of Electric Energy

A car battery, the chemical reaction that makes the electron that has the energy to move into an electric current. They provide electrical energy to the circuits attached to the moving charging car.

Electricity is a good example of electricity in nature, so powerful that it is not limited to one wire. Thundercloud produces electrical energy in large quantities. It is called static electricity. They are released during power when the clouds attack against each other.

What is Electric Power?

Generally, electricity is used to do some type of work, such as starting a motor or generating heat. In particular, power is the rate that works or the rate at which heat is generated. The unit used for specifying electrical power is the watt. In the equations, you will get the brief power with the capital letter P, and the units of measurement for watt, power, are abbreviated with the capital letter W. Power is also described as current (I) in a circuit time, voltage (E)) across the circuit.

Formula of Electric Power

P = I x E or P = IE

Using ohm’s Law for the value of voltage (E)

E = I x R

And using substitution Laws,

P = I x ( I x R )

The above equation is the power loss in a conductor of resistance R which carries the current I. The application of electric power is that it is transmitted from the power stations, which then reaches our homes and industrial factories through the transmission cable.
