Explanation:
a. if a current of 1 ampere flows through it when the potential difference across it is 1 volt
b. the electric power is the electric work done per unit time [P=W/T]. the relation between electric powe , potential difference and resistance is P=V2/R

Answer:
1 the rate at which electric energy is consumed in an electric circuit known as electric power.
2 the amount of work done in order to carry a charge from one point to another point is called potential difference.
3 it is used to measure the current flow in conductor or resist the over flow of current.
