Q. 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 I. Readings in $A$ are always in phase II. Reading in $V_{1}$ is ahead in phase with reading in $V_{2}$ III. Reading in $A$ and $V_{1}$ are always in phase. Which of these statements are/is correct
A) I only
B) II only
C) I and II only
D) II and III only
Explanation
(b) In $RC$ series circuit voltage across the capacitor leads the voltage across the resistance by $\frac{\pi}{2}$
