Power: The rate of doing work is called power.
                                 P=w/t
Power is measured in watts (w).
The watt is a small unit, so generally it is expressed in kilowatts (1o3w). mega watts(106w) etc.
"In electric circuit if voltage of (I) volt is present and the value of current is (I) ampere the power is one watt in this circuit.
                               P=VI
                            P=I x I = IW
