List of top Electrical Circuits Questions on Transient analysis of RLC circuits with dc excitation

A series RLC circuit is connected to 220 V, 50 Hz supply. For a fixed value of R and C, the inductor \(L\) is varied to deliver the maximum current. This value is 0.4 A and the corresponding potential drop across the capacitor is 330 V. The value of the inductor \(L\) is ______ H (rounded off to two decimal places).

A series RLC circuit with \(R=10\,\Omega\), \(L=50\text{ mH}\), \(C=100\ \mu\text{F}\) connected to \(200\ \text{V}\), \(50\ \text{Hz}\) supply consumes power \(P\). The value of \(L\) is changed such that the circuit consumes the same power but operates with lagging power factor. The new value of \(L\) is _____ mH (rounded off to two decimal places).

In the circuit given below, \(V_s = 50\ \text{V}\). Let the circuit reach steady state for the SPDT switch at position 1. Once the circuit is switched to position 2, the energy dissipated in the resistors is \(\underline{\hspace{1cm}}\) J (rounded off to one decimal place).
