What will be the power factor when the resistor voltage is 9 V at an angle of 30 degrees, and the capacitor voltage is 3 V at an angle of - 60 degrees in a RC series circuit? Also, what will be the power factor when the inductor voltage is 9 V at an angle of 45 degrees, and the resistor voltage is 3 V at an angle of - 45 degrees in a RL series circuit?
