Question

am electric heater of resistance 8ohm draws 15A current of 2 hours calculate the heat developed in the resistor​

Answer 1

Answer:

An electric heater of resistance 8 Ω draws 15 A from the service mains for two hours. ... Hence, the rate at which heat is developed in the electrical heater is 1800 Watt. Note: If instead of the current drawn by the heater, the potential difference across it (V) is given, the heat energy developed is given by V2Rt.
