An electric heater draws a constant current of 6 amps, with an applied voltage of 220 volts, for24 hours. Determine the instantaneous electric power provided to the heater, in kW, and the total amount of energy supplied to the heater by electrical work, in kW-h. If electrical power is valued at $0.08 / kW-h, determine the cost of operation for one day.
