Energy dissipates in LCR circuit in :

What is the ratio of inductive and capacitance reactances in an ac circuit?

An acceptor circuit is :

Series resonant circuit

Parallel resonant circuit

LCR circuit

None of these

In series resonant circuit:

Reactance is zero

Current is zero

Voltage is zero

None of these

To reduce the resonant frequency in an LCR series circuit with a generator

The generator frequency should be reduced.

Another capacitor should be added in parallel to the first.

The iron core of the inductor should be removed.

Dielectric in the capacitor should be removed.

A rejector circuit is:

Series resonant circuit

Parallel resonant circuit

LCR circuit

None of these

In pure inductive circuit current

Lags behind emf by π/2

Leads the emf by π/2

Lags behind emf by π

Leads the emf by π

An electric circuit containing capacitor only suffers:

Equal resistance for A.C. and D.C.

Resistance of A.C. > Resistance of D.C.

Resistance for A.C. < Resistance of D.C.

Offers infinite resistance for D.C.
