Electrical Energy


-->
Electrical energy is derived from electrical potential energy or energy that has been changed from electrical potential energy. 

In order for Electrical energy to be materialized a circuit is needed. The function of the circuit is to deliver the combination of electric current and electric potential, which is the driving force of electrical potential energy. After the electrical potential energy has been converted to another type of energy it stops behaving as electrical potential energy. Therefore, it can be said that electrical energy is actually a potential energy before it is being changed to other type of energy or energies.

1. Electrical energy is very important because this form of energy can be converted easily into other forms of energy, such as heat, light, mechanical and electromagnetic energy.


2. The energy carried by electrical charges can be transformed to other form of energy by using different electrical appliances. The table shows the transformation of energy for a few household appliances.


Appliances
Energy transformed
Rice cooker
Electrical to heat
Radio
Electrical to sound
Light
Electrical to heat and light
Washing machine
Electrical to mechanical

3. Electrical energy can be defined as the energy carried by electrical charges which can be transformed to other forms of energy by using of an electrical device or appliances.
