An impedance coil having a resistance of 15 ohms and an inductance of 0.08 henry is connected in series with a variable capacitor. If a 117 volt 60 cps source is connected to the circuit, what will be the capacitance of the capacitor and the current (a) when the circuit has a power factor of 0.866 leading and (b) when the voltage drop across the coil is equal to the voltage drop across the capacitor?
