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 ammeter

Now, consider the following statements :
(I) Reading in `A` and `V_(2)` 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

Options

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

Answer

A

Explanation

In `RC` series circuit voltage across the capacitance leads the voltage across the resistance by `(pi)/2`
