Problem
A series circuit has an impedance of 60.0Ω and a power factor of 0.720 at 50.0Hz. The source voltage lags the current.
(a) What circuit element, an inductor or a capacitor, should be placed in series with the circuit to raise its power factor?
(b) What size element will raise the power factor to unity?
