- C
- D
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Behaviour of impedance. In a series LCR circuit, impedance is minimum at resonance.
Step 2: Graphical interpretation. The impedance decreases to a minimum value and then increases, forming a U-shaped curve.
