What Is the LC Resonant Frequency?
The LC resonant frequency is the frequency at which a circuit made of a coil (L) and a capacitor (C) naturally oscillates. It is used in radio and filter circuits.
How is it calculated?
How Is It Calculated?
f = 1 ÷ (2π × √(L × C))
- Enter the coil (henry) and capacitor (farad) values.
Frequently Asked Questions
What happens at resonance?
The inductive and capacitive reactances become equal; the circuit gives its strongest response at that frequency.
