Power delivered by the source of the circuit becomes maximum, when

An alternating e.m.f. is applied to purely capacitive circuit. The phase relation between e.m.f. and current flowing in the circuit is or In a circuit containing capacitance only

A series ac circuit consist of an inductor and a capacitor. The inductance and capacitance is respectively $1$ henry and $25\mu F.$ If the current is maximum in circuit then angular frequency will be

In a series LCR circuit, operated with an ac of angular frequency $\omega$  ,the total impedance is

When $100$ volt dc is applied across a coil, a current of $1$ amp flows through it. When $100$  volt ac at $50$ cycle $s^{-1}$ is applied to the same coil, only $0.5$  ampere current flows. The impedance of the coil is
