Problem #1
The load in the circuit absorbs an average power of 80 W and a reactive power of 60 VAR. What is the power factor of the load? What are the values of the resistor and the inductor if v = 110 cos (2π60t) V?
Need a hint?
The power factor of the load is the real power divided by the apparent power. The equivalent impedance of the load can be found based on the power factor angle, the RMS value of the voltage and that of the current. The values of the resistor and inductor can be determined from the equivalent impedances.
