A house is maintained at a comfortable temperature by means of an electrical resistor heater during winter. The heater is operated at a constant current (I) under an applied voltage of 110 V. For simplicity, let us assume that the heater operates at a steady state, with 100% of conversion efficiency from the electrical energy to the internal energy of air in the house.

Required:
Find if the instructor pays $8.80/day for heating, with electricity cost $0.09/kWh.
b. Calculate the heat produced by such a heater hourly.
