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 phaseWhich of these statements are / is correct:

A
I only
B
II only
C
I and II only
D
II and III only

Solution

## The correct option is A $$II$$ onlyAs we know,In RC series circuit voltage across the capacitor leads the voltage across the resistance by $$\dfrac{\pi}{2}$$ hence,option B is correct.Physics
