In the given circuit, the potential difference across the $$6 \mu F$$ capacitor in steady state is 

In general in an alternating current circuit for a complete cycle

The natural frequency of an LC circuit is 125 kHZz. when the capacitor is totally filled with a dielectric material, the natural frequency decreases by 25 kHz. Dielectric constant of the material is nearly. 

The impedance of coaxial cable, when its inductance is 0.40 $$\mu H$$ and capacitance is 1$$\times { 10 }^{ -11 }$$ F can be 

A capacitor is connected to an A.C generator.The ratio of reactance and impedance of capacitor is-

When induced emf in inductor coil is $$50%$$ of its maximum value then stored energy in inductor coil in the given circuit will be-

Even if a physical quantity depends upon three quantites,out of which two are dimensionally same, then the formula cannot be derived by the method of dimensions.This statement.

In an LCR  circuit $$ R=100 \Omega $$ when capacitance C is removed, the current lags behind the voltage by $$ \pi / 3 $$. when inductance L is removed, the current leads the voltage by $$ \pi / 3 $$. the imoedance of the circuit is

An inductive circuit contains resistance of 10 ohms and an inductance of 20 H. If an A.c voltage of 120 volt and frequency 60 Hz is applied to this circuit , the current would be nearly

The alternating current in a circular is described by the graph as shown in figure. The rms current obtained from the graph would be
