JEE Mains · Physics · STD 12 -7. Alternating current
To increase the resonant frequency in series \(LCR\) circuit,
- 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 Another capacitor should be added in series with the first capacitor
Answer & Solution
Correct Answer
(C) Another capacitor should be added in series with the first capacitor
Step-by-step Solution
Detailed explanation
\(f =\frac{1}{2 \pi \sqrt{ LC }}\) To increase the resonating frequency product of \(L\) and \(C\) should decrease. By joining capacitor in series, capacitor will decrease
