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.

Explanation

Power of electric bulb `= 60 W`
`= 0.06 kW`.
Time used, `t = 6 h`
Energy = power `xx` time taken
`= 0.06 kW xx 6h`
`0.36 kWh`
= 0.36 units
The energy consumed by the bulb is `0.36` units.
