In an $LR$ circuit, the inductive reactance is equal to the resistance $R$ of the circuit. An emf $E=E_0\sin \left(\omega t\right)$ is applied to the circuit. The power consumed in the circuit is

In the circuit shown in figure, neglecting source resistance, the voltmeter and ammeter readings, respectively, will be

In the circuit shown in the figure, the ac source gives a voltage $V=20\cos \left(2000t\right)$. Neglecting source resistance, the voltmeter and ammeter readings will be

The diagram shows a capacitor $C$ and a resistor $R$ connected in series to an ac source. $V_1$ and $V_2$ are voltmeters and $A$ is an ammeter.

Consider the following statements:

$\mathrm{I}$. Readings in $A$ and $V_2$ are always in phase.
$\mathrm{II}$. Reading in $V_1$ is ahead in phase with reading in $V_2$.
$\mathrm{III}$. Readings in $A$ and $V_1$ are always in phase.

Which of these statements are/is correct?
