Solution: Click For PDF Version An electric motor connected to a 120-V, 60-Hz power outlet does mechanical
work at the rate of 0.10 hp (1 hp In an AC circuit the power dissipation, P, is related to the
rms current,
In our problem Therefore, the resistance of the motor is Yes, this would also be the resistance as measured by an ohm-meter with the
motor disconnected from the outlet. In an AC circuit the impedance
depends on the frequency of the mains and the values of circuit elements L
and C and the R, and the
