List of top Physics Questions on LCR Circuit asked in JEE Main

A battery of 6V is connected to the circuit as shown below. The current I drawn from the battery is

In the given circuit, the value of current \(I_L\) will be __________ mA. (When \(R_L = 1\ kΩ\))

An LCR circuit contains resistance of $110 \Omega$ and a supply of $220 V$ at $300 rad / s$ angular frequency. If only capacitance is removed from the circuit, current lags behind the voltage by $45^{\circ} .$ If on the other hand, only inductor is removed the current leads by $45^{\circ}$ with the applied voltage. The $rms$ current flowing in the circuit will be :

As given in the figure, a series circuit connected across a $200V,60Hz$ line consists of a capacitor of capacitive reactance $30\mathrm{\Omega }$, a non-inductive resistor of $44\mathrm{\Omega }$, and a coil of inductive resistance $90\mathrm{\Omega }$ and resistance $36\mathrm{\Omega }$. The power dissipated in the coil is?

In a series LCR Circuit, the value of resistance as well as (X_L - X_C) is halved, then the new current amplitude (I₂) will satisfy: (I₁ is old current amplitude)
