JEE Main & Advanced Physics Electro Magnetic Induction Question Bank Mock Test - Electromagnetic Induction

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

A) I only

B) II only

C) I and II only

D) II and III only

Correct Answer: B

Solution :

[b] In RC series circuit voltage across the capacitor leads the voltage across the resistance by \[\pi /2\]
