Question

An inductor `L`, a capacitor `C` and `AC` ammeters `A_(1),A_(2)` and `A_(3)` are connected in the circuit as shown. When the frequency of the oscillators is increased, then at resonant frequency, the reading of ammeter ?

A. `A_(1)` zero
B. `A_(2)` zero
C. `A_(3)` zero
D. is same in `A_(1),A_(2)` and `A_(3)`

Answer 1

Correct Answer - A
At resonant `omegaL=1/(omegaC)`. So, reading of `A_(1)` is zero.
