What is the reading in the $AC$ ammeter for the $AC$ circuit shown in the figure?

The value of the alternating emf in the given series $LCR$ circuit is: (in $V$)

$A$ series $R-L-C$ circuit consists of an $8.0\ \Omega$ resistor,a $5.0\ \mu F$ capacitor,and a $50.0\ mH$ inductor. $A$ variable frequency source applies an $emf$ of $400\ V\ (rms)$ across the combination. The power delivered to the circuit when the frequency is equal to one-half the resonance frequency is.....$W$

In an $R-L-C$ series circuit, the potential difference across each element is $20 \, V$. If the value of the resistance $R$ is doubled, what will be the potential difference across $R, L$, and $C$ respectively?

If a resistance of $100\, \Omega$,an inductance of $0.5\, H$,and a capacitance of $10 \times 10^{-6}\, F$ are connected in series to a $50\, Hz$ $AC$ supply,then the impedance is:

In an $LCR$ circuit shown in the following figure,what will be the readings of the voltmeter across the resistor and ammeter if an $a.c.$ source of $220\,V$ and $100\,Hz$ is connected to it as shown?
