The self-inductance of a solenoid of length $l$, area of cross-section $A$ and number of turns $N$ is proportional to

In an AC circuit containing only an inductor, the current [H] [width=0.5\linewidth]{113.png}

Resonance frequency of an LCR series AC circuit is \(f_0\). Now inductance is reduced to \(\dfrac{1}{4}\) times and capacitance is increased to \(16\) times, then the resonance frequency becomes:

An RLC circuit consists of a \(150\,\Omega\) resistor, \(20\,\mu\text{F}\) capacitor and a \(500\,\text{mH}\) inductor connected in series with a \(100\,\text{V}\) AC supply. The angular frequency of the supply voltage is \(400\,\text{rad s}^{-1}\). The phase angle between current and the applied voltage is

Consider a series LCR circuit connected to an AC source. The resistance, inductive reactance and capacitive reactance are \(R, X_L, X_C\) respectively. If the current in this circuit lags the source voltage then the correct option is:

In an oscillating LC circuit, \(L = 1.6\,mH\), \(C = 4\,\mu F\). If the maximum charge is \(4 \times 10^{-6}\,C\), then the maximum current is:

An inductor of reactance \(1\,\Omega\) and a resistor of resistance \(3\,\Omega\) are connected in series to the terminals of \(10\,\text{V}\) (rms) ac source. The power dissipated in the circuit is
