As part of a lab exercise, Sam is given an unknown capacitor and inductor and asked to determine the reactance of the circuit. He connects the inductor and capacitor in

series with a resistor and an AC voltage source. He measures the rms current and rms voltage to be $14\mathrm{.}0$A and $175V,$ respectively, and determines that the voltage lags

behind the current by $30\mathrm{.}0.$ What value does Sam get for the reactance of the circuit?

What is the expression for the power in terms of the rms current, rms voltage, and power factor? How is the power related to the resistance in an AC circuit? What is the

resistance used in the circuit? If the voltage lags behind the current, what is the sign of the phase? $$
