## A vacuum cleaner is plugged into a 120.0-V socket and uses 3.0 A of current in normal operation when the back emf generated by the electric motor is 72.0 V Find the coil resistance of the motor?

Stable voltage across the motor = (120 - 72) = 48 VR = E / I = 48/3 = 16 ohms.(Assumes power-factor of 1, no reactances, back-emf in phase with the line, etc.)

## You plug a vacuum cleaner into a 110-V outlet with nothing else on the circuit If the 15-A circuit breaker is tripped. what is the maximum possible resistance of the vacuum's motor?
