a heater and a motor are powered in parallel from the same 220v power supply. the motor draws 2A and the heater draws 17A.
a) what is the resistance of the motor? asume it is pure resistive
b) what is the resistance of the heater?
c) what is the total power dissipated by the dryer?
d) if the dryer runs for 8hrs per week how much does it cost to operate it for 1 year? assume that electricity costs $0.17/kwh.
