Tesla Coil Calculator

Building a Tesla coil is a complex endeavor that requires a precise understanding of various components and their interactions. A calculator for a Tesla coil would likely take into account factors such as wire gauge, number of turns, primary and secondary coil diameters, capacitor value, and resonant frequency.

However, building a complete Tesla coil calculator in this space would be too expansive. Instead, let’s focus on a simplified version that will calculate the resonant frequency of the secondary coil, which is an important value for Tesla coil builders.
