a.c circuit containing capacitance only

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

Discuss the phase relationship between current and emf in an circuit containing a capacitance only.

The current in a circuit containing a capacitance C and a resistance R in series leads over the applied voltage of frequency omega/(2pi) by.

In a pure inductive circuit or In an ac circuit containing inductance only, the current

Let f = 50 Hz, and C = 100 muF in an AC circuit containing a capacitor only. If the peak value of the current in the circuit is 1.57 A at t = 0. The expression for the instantaneous voltage across the capacitor will be

In an AC circuit containing only capacitance the current

In a series AC circuit containing a capacitor and a resistor only

An alternating e.m.f. is applied to a circuit containing an inductance and a capacitance in series. It is found that for a particular frequency 'f' of the A.C. Genrator, the current in the circuit is maximum. If L=1/(2 pi) Henry and c = 1/(2pi) muF , then the reasonant frequency is
