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

Energy consumed by an electric heater can be obtained with the help of the expression, P= W/T Where, Power rating of the heater, P= 1500 W = 1.5 kW Time for which the heater has operated, T= 10 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 10 h is 15 kWh.
