Answers
Answer:
The energy which is caused by the movement of the electrons from one place to another such type of energy is called electrical energy. ... Electrical energy is the form of kinetic energy because it produces by the movement of the electrical charges.

Answer:
Electric power is the rate at which electric energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second.
It is the rate of doing work, measured in watts, and represented by the letter P. The electric power in watts produced by an electric current I consisting of a charge of Q coulombs every t seconds passing through an electric potential (voltage) difference of V is
P= work done per unit time = VQ/t =VI
where,
Q is electric charge in coulombs
t is time in seconds
I is electric current in amperes
V is electric potential or voltage in volts.
