  1. Question 1

    Q1. In an LCR circuit, why does the current reach a maximum at resonance frequency?

    • A) Impedance becomes purely resistive
    • B) Inductive reactance cancels resistive reactance
    • C) Capacitive reactance cancels inductive reactance
    • D) Voltage across inductor exceeds capacitor voltage

    Answer: Capacitive reactance cancels inductive reactance

    Explanation: At resonance, X_L = X_C cancelling each other. Option B incorrectly suggests reactance cancels resistance.
