Question

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.

Now, consider the following statements:
I. Readings in $A$ and $V_2$ are always in phase.
II. Reading in $V_1$ is ahead in phase with reading in $V_2$
III. Readings 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

Answer 1

Answer: (B)

In $RC$ series circuit, voltage across the capacitor leads the voltage across the resistance by $\frac{\pi }{2}$.
