In a parallel resonant circuit, the input impedance of the circuit is _______.

Resonance in an electrical circuit

• Electrical resonance is defined as the condition when the magnitude of capacitive reactance(X_C) becomes equal to that of inductive reactance(X_L). As a result of resonance, maximum current flows through the RLC circuit.
• Parallel resonance is a resonance condition that usually occurs in parallel circuits, where the voltage becomes a maximum for a given current. Being a parallel resonance means the impedance is high and the inrush surge current is relatively low compared to a simple capacitor.
