JEE Mains · Physics · STD 12 -7. Alternating current
In a scries \(LCR\) resonance circuit, if we change the resistance only, from a lower to higher value
- A The bandwidth of resonance circuit will increase.
- B The resonance frequency will increase.
- C The quality factor will increase.
- D The quality factor and the resonance frequency will remain constant.
Answer & Solution
Correct Answer
(A) The bandwidth of resonance circuit will increase.
Step-by-step Solution
Detailed explanation
Bandwidth \(= R / L\) Bandwidth \(\propto R\) So bandwidth will increase
