2.Electrical Power and its Expression For Class 10


Electrical Power: Rate of electrical energy supplied by a source e.g. a power station or an alternator or a dc battery etc is called electrical power.

∴ Power = Electrical Energy supplied / Time
if Power = P
Energy supplied = W
and Time = T
Then P = W / T
if W is in Joul
T in second
then unit of power will be Joul/Second (J/S); which is called watt.
∴ watt = j/s
∴Electrical Power, P=W/t=V.I=V2/R=I2.R
