A circuit consists of a series connected 84 Ω resistor and a 163 mH inductor. The circuit supply is a 121 V rms source with a frequency of 42 Hz. Ultimately, you need to calculate the average power dissipated in the circuit. You should have found the polar form of the complex current. The average power dissipated in the resistive and reactive circuit is: ?=??cosφ where φ is the phase of the current, and V and I are the rms values. Finally, calculate the circuit Power Factor (cos?) where φ is the phase of the current. Finally, will the circuit Power Factor cos? be lagging or leading?
