Answer:
2 Answers. Power= 1500w=1500/1000=1.5kw Time=10 hours Energy=power×time 1.5×10 =15kW
Explanation:
Energy consumed by an electric heater can be obtained with the help of the expression, P= W/T
Energy consumed by an electric heater can be obtained with the help of the expression, P= W/TWhere,
Energy consumed by an electric heater can be obtained with the help of the expression, P= W/TWhere,Power rating of the heater (P) = 1500
Energy consumed by an electric heater can be obtained with the help of the expression, P= W/TWhere,Power rating of the heater (P) = 1500W = 1.5 kW = 1500 W
Energy consumed by an electric heater can be obtained with the help of the expression, P= W/TWhere,Power rating of the heater (P) = 1500W = 1.5 kW = 1500 WTime for which the heater has operated (T) = 10 h
Energy consumed by an electric heater can be obtained with the help of the expression, P= W/TWhere,Power rating of the heater (P) = 1500W = 1.5 kW = 1500 WTime for which the heater has operated (T) = 10 hWork done = Energy consumed by the heater
Energy consumed by an electric heater can be obtained with the help of the expression, P= W/TWhere,Power rating of the heater (P) = 1500W = 1.5 kW = 1500 WTime for which the heater has operated (T) = 10 hWork done = Energy consumed by the heater∴ Energy consumed = Power × Time
Energy consumed by an electric heater can be obtained with the help of the expression, P= W/TWhere,Power rating of the heater (P) = 1500W = 1.5 kW = 1500 WTime for which the heater has operated (T) = 10 hWork done = Energy consumed by the heater∴ Energy consumed = Power × TimeEnergy consumed = 1500 × 10
Energy consumed by an electric heater can be obtained with the help of the expression, P= W/TWhere,Power rating of the heater (P) = 1500W = 1.5 kW = 1500 WTime for which the heater has operated (T) = 10 hWork done = Energy consumed by the heater∴ Energy consumed = Power × TimeEnergy consumed = 1500 × 10Energy consumed = 15000 W
Energy consumed by an electric heater can be obtained with the help of the expression, P= W/TWhere,Power rating of the heater (P) = 1500W = 1.5 kW = 1500 WTime for which the heater has operated (T) = 10 hWork done = Energy consumed by the heater∴ Energy consumed = Power × TimeEnergy consumed = 1500 × 10Energy consumed = 15000 WHence, the energy consumed by the heater in 10 h is 15 kWh.
