Tesla Coil Resonant Transformer (2D)

Interactive 2D Tesla coil: tune the secondary's toroid capacitance against the fixed primary tank frequency, adjust coupling and drive voltage, and watch the resonant rise produce streamer arcs whose length tracks the computed output voltage.

This 2D cross-section models a Tesla coil as two coupled resonant LC tanks: a fixed-frequency primary at the base and a tall secondary topped by a toroid whose capacitance you tune. Drag the tuning slider toward 100% to bring the secondary's resonant frequency onto the primary's, watch the live match percentage climb, and see the output voltage — and the branching streamer arcs jumping off the toroid — grow accordingly.

⚙ Under the hood

A 2D companion to the 3D Tesla coil: tune the secondary's toroid capacitance against the fixed primary tank frequency, adjust the magnetic coupling and drive voltage, and watch the resonant rise drive branching streamer arcs whose length tracks the computed output voltage via air's ~3 MV/m breakdown field.
