Q10 of 19 Page 374

An electric bulb of 60 W is used for 6 h per day. Calculate the ‘units’ of energy consumed in one day by the bulb.

Given

Power = 60 W =


(∵ 1Kw = 1000 W).


Time (t) = 6 hours.


Now


Power =


⇒ Energy Consumed = Power × Time taken


= 0.06 × 6 = 0.36kWh


Hence 0.36 unit of electricity is consumed by a bulb in one day.
