Question

In LCR circuit if resistance increases, then quality factor

• A. increases finitely
• B. decreases finitely
• C. remains constant
• D. None of these

Answer 1

The correct option is B decreases finitely

Quality factor $Q$ is given by:
$Q=\frac{{\omega }_{0}L}{R}$
Thus, as $R$ increases $Q$ definitely decreases.
