Resonance in an RLC circuit occurs when:

A R = L

B Inductive reactance equals capacitive reactance (XL = XC), impedance is purely resistive

C All components are equal

D Frequency is zero

✓ Correct Answer: Option B

Resonance: XL = XC → ωL = 1/(ωC) → ω₀ = 1/√(LC). At resonance, impedance is minimum (= R), current is maximum.

💡 Why is B) the correct answer?

The correct answer to the question "Resonance in an RLC circuit occurs when:" is Option B: Inductive reactance equals capacitive reactance (XL = XC), impedance is purely resistive.

The other options — A) R = L, C) All components are equal, D) Frequency is zero — are incorrect for this FE Exam Prep question. As explained above: Resonance: XL = XC → ωL = 1/(ωC) → ω₀ = 1/√(LC). At resonance, impedance is minimum (= R), current is maximum.
