A voltage source V = V0 sin(ωt + Φ) is applied to a circuit containing a resistance ‘R’, capacitance ‘C’ and inductance ‘L’ in series. The current will be maximum when:

An inductance of 300/π mH, a capacitance of 1/π mF and a resistance of 20 Ω are connected in series with a.c. source of 240 V, 50 Hz. The phase angle by which the voltage leads the current in the circuit is

In an L-C circuit, angular frequency at resonance is ‘ω’. If the inductor’s inductance is made twice and capacitor’s capacitance is made four times, the new angular frequency at resonance will be :

A coil having an inductance of 1/π H is connected in series with a resistance of 300 Ω. If A.C. source (20 V-200 Hz) is connected across the combination, the phase angle between voltage and current is :

In LCR series resonance circuit, choose the wrong statement

A capacitor 50 µF is connected to a.c. source e = 220sin 50 t (e in volt, t in second). The value of peak current is:

In series LCR circuit, the voltage across. L, C and R is 50 V, 20 V and 40 V respectively. The a. c. voltage applied across the combination of LCR is

In series L-C-R circuit C = 2µF, L = 1mH and R = 102. What is the ratio of energies stored in the inductor and the capacitor, when the maximum current flows in the circuit

When a. c. source is connected across a pure resistor, the correct phase relation between current (iR) and voltage (eR) is shown in figure

The instantaneous values of current and voltage in a AC circuit are given by: I = 6 sin (100πt + π/4) and V=5 sin (100πt -π/4) then
