A circuit of negligible resistance has an inductor of 0.16 H and capacitor of 25 µF connected in series with an alternating voltage source. The resonating frequency of the circuit is:

In series L-C-R circuit, the capacitance is changed from ‘C’ to ‘2C”. To obtain the same resonance frequency the inductance should be changed from ‘L’ to :

An inductance coil has a resistance of 100 2. When an a.c. signal of frequency 100 Hz is applied to the coil, the voltage leads the current by 45°. The inductance of the coil in henry is

Resistor of 2 Ω, inductor of 100 µΗ and capacitor of 400 pF are connected in series across an a.c. source of erms= 0.1 volt. At resonance, voltage drop across inductor is:

If the voltage in an a. c. circuit is represented by the equation V = 220sin(314t – phi) then r.m.s. value of the voltage is:

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

In an a. c. circuit I = 100 sin 200 πt. The time required for the current to achieve its peak value will be:

A 120 V a.c. source is connected across a pure inductor of inductance 0.70 H. If the frequency of the source is 60 Hz, the current passing through the inductor is (Neglect spin motion): (Taken π = 22/7)
