Phase difference between voltage and current in a capacitor in an ac circuit is

The power factor of an, ac circuit is 0.5 Phase , difference between voltage , and current in this circuit is

The power factor of an AC circuit is 0.5 . What will be the phase difference between voltage and current in this circuit ?

The phase difference between voltage and current in an LCR series circuit is

The phase difference between voltage and current in an AC circuit containing a resistor and an inductor in series is phi_1 . When the inductor is replaced by a capacitor , the phase difference is changed to phi_2 . The phase difference when all the three elements are connected in series with the same AC source will be
