Alternating CurrentHard
Question
A resistor R, an inductor L, a capacitor C and voltmeters V1, V2 and V3 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 :


Options
A.voltmeter V1
B.voltmeter V2
C.voltmeter V3
D.all the three voltmeters
Solution
At resonance voltages across C and L are in opposite phase so net voltage will be zero.
So, V2 = 0.
So, V2 = 0.
