In a series LCR circuit $X_L = X_C$. Which of the following is correct?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → The current amplitude is maximum
In a series LCR circuit, at resonance:
$X_L = X_C \Rightarrow \text{Reactances cancel}$
At resonance:
- Impedance $Z = R$ (minimum)
- Current amplitude $I_{\max} = \frac{V}{R}$ (maximum)
- Current is in phase with voltage
Given options:
Correct statement: The current amplitude is maximum
