Answer:

hi there!!

Explanation:

happy helping ❤️

In a LCR circuit, the quality factor can be improved by

Q-factor: In LCR Circuit, the ratio of resonance frequency to the difference of its neighbouring frequencies so that their corresponding current is 1/ root 2 timess of the peak value, is called Q-factor of the circuit.

Formula: Q=

$1 \div r \sqrt{l \div c}$

Conditions for the large value of Q factor:

(i) Value of c/l should be large

(ii) Value of R should be less.
