Figure 20.7
(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
