Question 115 of 190

In a scries LCRLCR resonance circuit, if we change the resistance only, from a lower to higher value :

Show answer and solution

Answer: (A) The bandwidth of resonance circuit will increase.

The bandwidth of resonance circuit will increase.
As we know that Bandwidth =R/L=R/L.
Bandwidth ∝R\propto R.
So, bandwidth will increase.
