The series or parallel resonant frequency of an inductor and a capacitor can be calculated using the following equation. A FLEXI-BOX is available with a transmission line PCB and a selection of connectors for building this as a test aid. The PCB can easily be modified for this circuit and many others.
f is the Frequency in Hz
C is the Capacitance in Farads
L is the Inductance in Henries
This calculator is provided free by Chemandy Electronics in order to promote the FLEXI-BOX
