An ac source is initially connected to a resistor R Situation 1 If an inductor is connected in series with the resistor the impedance in the circuit is 3R Situation 2 If a capacitor is connected in series with resistor the in is 2R e cire 4 36 Situation 3 Both the inductor and the capacitor are connected in series to the resistor A In situation 3 if the phase of current and potential difference across the source is then cot pr where p is nearly
