With a gradual increase in the frequency of an $A.C.$ supply, the impedance of an $LCR$ series circuit

In a parallel $AC$ circuit with $R_1 = R_2 = R$ and $X_L = X_C = X$. An $AC$ source $V = V_0 \sin(\omega t)$ is connected across the circuit as shown in the figure. The $RMS$ value of the potential difference $V_A - V_B$ will be:

An inductor of reactance $100 \text{ } \Omega$, a capacitor of reactance $50 \text{ } \Omega$, and a resistor of resistance $50 \text{ } \Omega$ are connected in series with an $AC$ source of $10 \text{ V}$, $50 \text{ Hz}$. Average power dissipated by the circuit is (in $\text{ W}$)

For a series $LCR$ circuit,$R = X_L = 2X_C$. The impedance of the circuit and the phase difference between $V$ and $I$ respectively will be:

In a series $LCR$ circuit,the voltages across $R, L$ and $C$ are shown in the figure. The voltage of the applied source is ........ $V$. (in $, V$)

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