Q. To increase the resonant frequency in series LCR circuit,
JEE Main
JEE Main 2022
Alternating Current
A
Source frequency should be increased
B
Another resistance should be added in series with the first resistance.
C
Another capacitor should be added in series with the first capacitor
D
The source frequency should be decreased
Solution:
$f=\frac{1}{2 \pi \sqrt{L C}}$
To increase the resonating frequency product of $L$ and $C$ should decrease.
By joining capacitor in series, capacitor will decrease
