With this application with free unknown is possible to obtain :

**Capacity**value from inductance and resonant frequency.**Inductance**value from capacity and resonant frequency.**Resonant frequency**from capacity and inductance.

The unknown value is free, it can be any of the three.

Every input and output values can be express with any avaible measure units.

At the resonant frequency, we've got the minor resistance
of the circuit, the value of the resistance at the resonant frequency depends
on Q of the circuit.

The highest Q is obtained with capacitor C and parasitic capacitance minor as possible.

The Q factor determines also the bandwidth, with elevated Q we obtain close curve
of resonance, with low Q we obtain large curve of resonance.

Resonant frequency (L, C or Rf unknown).

Select the value to obtain:

L unknown

C unknown

Fr unknown
