(a) Given the voltage source is 120 V, the wire resistance R1 is 0.400 omegacap.gif, and the bulb is nominally 70.0 W, what power will the bulb dissipate if a total of 32.0 A passes through the wires when the motor comes on? Assume negligible change in bulb resistance.
W

(b) What power is consumed by the motor?
kW
