An ideal resistance R, ideal inductance L , ideal capacitance C and AC voltmeters `underset(1)(V)` , `underset(2)(V)` , `underset(3)(V)` and `underset(4)(V)` are connected to an AC source as shown . At resonance

A

Reading in `V_(3)` = reading in `V_(1)`

B

Reading in `V_(1)` = reading in `V_(2)`

C

Reading in `V_(2)` = reading in `V_(4)`

D

Reading in `V_(2)` = reading in `V_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D

At resonance
`V_(L) = V_(C) rArr ` Reading in `V_(2) ` = reading in `V_(3)`
