Q17 of 41 Page 461

An electric lamp is marked 26 W, 220V. It is used for 10 hours daily. Calculate

energy consumed in kWh per day.

Energy = Power × time

⇒ Energy = 26 × 10 = 260 W


We divide by 1000 for converting in Kw


Energy Consumed =


Hence the energy consumed is 0.26 KW

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.
