Answer:
Electrical energy is the energy derived from the electric potential energy or kinetic energy of the charged particles. In general, it is referred to as the energy that has been converted from electric potential energy. Electrical energy can be defined as energy generated by the movement of electrons from one point to another. The movement of charged particles along/through a medium constitute current or electricity.
The commercial unit of electrical energy is a kilowatt-hour (kWh).
To convert 1kWh into joule
1kWh = 1000 × 60 × 60
1kWh = 3.6 × 106 J
The electric energy used in factories, industries and houses which are measured in kWh.
