Question

If an electric bulb of 100 watt is lighted for 2 hours and a fan of 110 watt is used for 1 hour. how much electrical energy will be consumed in kWh?

Answer 1

Answer:

Energy Consumed is expressed in kiloWatt hour (kWh) or what we commonly call as unit

Energy = Power x Time

(for getting Energy in “kiloWatt hour or unit”, make Power in kilo Watts and Time in Hours).

So Here,

Power = 100 Watts or 0.1 kilo Watts

Time = 2 Hours

So Energy (in kWh or Unit) = 0.1 kW x 2 hour = 0.2 kWh or 0.2 Unit
