Alternating Cur...

In series LCR circuit, the capacitance is changed from $$C$$ to $$2C$$. The inductance should be changed from $$L$$ to ______ to obtain same resonance frequency.

In an LCR circuit, the capacitance is made one-fourth, when in resonance. Then what should be the change in inductance, so that the circuit remains in resonance?

In resonance, frequency of LC circuit is :

Symbol of Inductance in electric circuit is-

The peak voltage of an AC supply is $$300V$$. What is the rms voltage?

The rms value of current in an AC circuit is $$10A$$. What is the peak current?

The current which does not contribute to the power consumed in an AC circuit is called:

The power loss is less in transmission lines, when :

When the frequency of the source voltage decreases, the impedance of a parallel RC circuit

In $$L-C-R$$ series circuit, the capacitor is changed from $$C$$ to $$4C$$. For the same resonant frequency, the inductance should be changed from $$L$$ to.
