Question: In a scries LCR resonance circuit, if we change the resistance only, from a lower to higher value :
The bandwidth of resonance circuit will increase.
The resonance frequency will increase.
The quality factor will increase.
The quality factor and the resonance frequency will remain constant.
Correct Option: 1
Solution:
Bandwidth $=\mathrm{R} / \mathrm{L}$
Bandwidth $\propto \mathrm{R}$
So bandwidth will increase
