Inductance (Henrys):

A Capacitance-Frequency-Inductance Calculator helps determine the relationship between capacitance, frequency, and inductance in resonant circuits — particularly for LC (inductor-capacitor) circuits. It's mostly used in radio, signal processing, and oscillator design.

The key formula comes from the LC resonance equation:


Where:
f = Resonant frequency (in hertz, Hz)
L = Inductance (in henries, H)
C = Capacitance (in farads, F)
You can rearrange the formula depending on what you're solving for:

Frequency:


Example Calculation:
Let's say you have an inductor of 10 mH (0.01 H) and a capacitor of 100 nF (0.0000001 F):


So the circuit resonates at about 159.15 kHz.
