Question

The diagram shows a capacitor $C$ and a resistor $R$ connected in series to an $AC$ source, $V_1$ and $V_2$ are voltmeter and $A$ is an ammeter. Consider now the following statements:
(I) Reading in $A$ and $V_2$ are always in phase
(II) Reading in $V_1$ is ahead 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

Answer 1

Answer: (B)

$II$ only

As we know,

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

hence,

option B is correct.
