In an A.C. Circuit containing an inductance and a capacitance in series, the current is found to be maximum, when L=0.5H and C=8 muF . Then the angular frequency of the applied alternating e.m.f. will be

For an A.C. Circuit, contianing a resistance and a capacitance in series, the angle between current and e.m.f. is given by tan theta = 1(omega CR) . The power factor of this circuit is

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.

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
