Question: A two branch tuned circuit has a coil of resistance R and inductance L in one branch and capacitance C in the second branch. If R is increased, the dynamic resistance
[A].

decreases

[B].

increases

[C].

remains constant

[D].

may increases or decreases

Answer: Option B

Explanation:

Dynamic resistance = and increases as L is increased.
