An electric fan runs from the 230 V mains. The current flowing through it is 0.4 A. At what rate is electrical energy transferred by the fan?
Here, V = 230V, I = 0.4amp
We know that power is the rate at which electric energy is transferred
P = V x I
= 230 x 0.4
= 92 W = 92 J/s

The electric power consumed by a device may be calculated by the using either of the two expressions P = I2R or P = V2/R. The first expression indicates that it is directly proportional to R whereas the second expression indicates inverse proportionality. How can the seemingly different dependence of P on R in these expressions be explained.Together With Science
