Define Electric power
1.
One watt is the power consumed when an electric device is operated at a potential difference of one volt and it carries a current of one ampere. A larger unit of power, which is more commonly used is kilowatt.
2.
The SI unit of electric power is watt. When a current of 1 ampere passes across the ends of a conductor, which is at a potential difference of 1 volt, then the electric power is P = 1 volt x 1 ampere = 1 watt.
3.
The electric power is the product of the electric current and the potential difference due to which the current passes in a circuit.
4.
A current ‘I’ flows through a conductor of resistance ‘R’ for a time ‘t’, then the potential difference across the two ends of the conductor is ‘V’ The work done ‘W’ to move the charge across the ends of the conductor is given by the equation.
W = V I t, Power P = work/time = V I t/t. P= V I.
5.
The electric power is defined as the rate of consumption of electrical energy. It represents the rate at which the electrical energy is converted into some other form of energy.
