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.
