Formula
$$ f = {1 \over 2π~\sqrt {LC} } $$
Resonant LC
If a charged capacitor is connected across an inductor, charge will start to flow through the inductor, building up a magnetic field around it, and reducing the voltage on the capacitor.
Elements
- L : Inductor Henry H
- R : Capacitive Farad F
- F : Frequency Hertz Hz
Examples:
What is a resonant frequency for a circuit with a capacitor with 10pF and a coil with 10H.
C=10pF
L=10H
f=15.915,5 Hz
