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 now 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.
