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.
