Question

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

Answer 1

Energy consumed in KiloWattHour means energy consumed in units.

Power of the bulb = 60W = 0.06kW
It is used for 6 hours, so t = 6.
Therefore, Energy = Power x time
= 0.06kW x 6 h
= 0.36kWh
=0.36units

Answer 2

Power of electric bulb = 60 w

                                     = 0.06 kw

Time used  = 6 h

Energy = power * time

             = 0.06 * 6

             = 0.36 Kwh

             = 0.36 'units'

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

Hope this answer help you
