A heater of 400 Watt was on for 5 hours. What is the electrical consumption?
Correct answer: C. 2 KWh
- A. 20 KWh
- B. 12 KWh
- C. 2 KWh
- D. None of the above
Explanation
Electrical energy consumption is calculated as Power × Time. First, convert power to kilowatts: 400 W = 0.4 kW. Then, multiply by the time in hours: Energy = 0.4 kW × 5 h = 2 kWh.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
