An electric heater is rated 1500 W. How much energy does it use in 10 hours?

Asked by Vishal kumar | 2 years ago |  372

##### Solution :-

With the help of the expression, energy consumed by an electric heater will be obtained,

P = T

Where, Power rating of the heater,

P = 500 W = 1.5 power unit Time that the heater has operated,

T = ten h Work done = Energy consumed by the heater

Therefore, energy consumed = Power × Time

= 1.5 × 10 = 15 kWh

Hence, the energy consumed by the heater in 10h is 15 kWh
