A resistor `R`, an inductor `L`, a capacitor `C` and voltmeters `V_(1),V_(2)` and `V_(3)` are connected to an oscillator in the circuit as shown in the adjoining diagram.When the frequency of the oscillator is increased, upto resonance frequency, the voltmeter reading (at resonance frequency) is zero in the case of:

A

voltmeter `V_(1)`

B

voltmeter `V_(2)`

C

voltmeter `V_(3)`

D

all of three voltmeters

Text Solution

Verified by Experts

The correct Answer is:
B
At resonance voltages across `C` and `L` are in opposite phase so net voltage will be zero.
So` V_(2)=0`.
