Question

In LCR- circuit if resistance increases, quality factor

A

Increases finitely

B

Decreases finitely

C

Remains constant

D

None of these

Answer

Decreases finitely

Explanation

Solution

: Here, $\theta = \frac{\omega^{2}L}{R}$

If R resistance increases, quality factor $\theta$ decreases finitely.
