Question

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.

Answer 1

❄️ Answer with solution :

Power of electric bulb = 60 W

= 0.06 kW.

Time used, t = 6 h

Energy = power × time taken

= 0.06 kW × 6 h

= 0.36 kW h

= 0.36 'units'.

The energy consumed by the bulb is 0.36 'units'.
