Electrical Resonance
Electrical resonance occurs when an electrical circuit's inductance (coil) and capacitance (capacitor) are tuned to a specific frequency, causing them to exchange energy efficiently. At this resonant frequency, the circuit's impedance (resistance to current flow) is at a minimum (for series circuits) or maximum (for parallel circuits), allowing the circuit to respond strongly to that frequency. This phenomenon enables applications like tuning radios to specific stations or efficiently transmitting power. Essentially, electrical resonance amplifies certain signals by allowing energy to cycle smoothly between the magnetic field of the inductor and the electric field of the capacitor.
