Question:easy

In an LCR series circuit, at resonance,

Show Hint

At resonance X_L = X_C so the impedance is minimum and equal to R.
Updated On: Oct 1, 2026
  • the impedance is maximum
  • the current is minimum
  • the current leads the voltage by \(\frac{π}{2}\)
  • the current and voltage are in phase
Show Solution

The Correct Option is D

Solution and Explanation

Step 1: Condition
Resonance means $X_L = X_C$.

Step 2: Consequences
$Z = R$ (minimum), $I$ maximum, phase difference zero.

Step 3: Match
Only option (D) states this.

Final Answer:
Option (D). \[ \boxed{\text{In phase}} \]
