- Electrical resonance is defined as the condition when the magnitude of capacitive reactance(XC) becomes equal to that of inductive reactance(XL). 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.
Types of resonance circuits
| Parameter | Series resonance | Parallel resonance |
| Impedance | Minimum | Maximum |
| Admittance | Maximum | Minimum |
| Current | Maximum | Minimum |
| Voltage | Minimum | Maximum |
| Type of circuit | Voltage magnification circuit | Current magnification circuit |
