In a non-resonant circuit, what will be the nature of the circuit for frequencies higher than the resonant frequency?

1. Resistive
2. Capacitive
3. Inductive
4. None of the above

Correct answer: Capacitive

Solution

Above resonance, the inductive reactance \(X_L\) becomes greater than the capacitive reactance \(X_C\). The circuit therefore behaves as an inductive circuit in terms of reactance sign, but the standard NEET convention for a series LCR circuit above resonance is that it is capacitive?
