At resonance, inductive and capacitive reactances are equal, creating minimum impedance for series circuits.
Measures the sharpness of resonance and energy storage efficiency in the circuit.
Enter the inductance (L) and capacitance (C) values. Click Calculate to find the resonant frequency, quality factor, and bandwidth of the LC circuit.
L = 10mH, C = 100μF: fr = 1 ÷ (2π × √(0.01 × 0.0001)) = 159.2 Hz.
A: At resonance, inductive reactance equals capacitive reactance (XL = XC). The circuit has minimum impedance in series or maximum in parallel.
A: Q factor measures the sharpness of resonance. High Q means sharp, selective frequency response. Q = Energy stored ÷ Energy dissipated per cycle.
A: Bandwidth is the range of frequencies around resonance where power is at least half the maximum: BW = fr ÷ Q.
A: Radio tuning circuits, bandpass filters, oscillators, wireless power transfer, and impedance matching networks.
