In this project, I constructed a Tesla coil using a TIP 41C transistor. The main setup includes a 560-turn secondary coil made from 31-gauge copper wire and a 2-turn primary coil of 18-gauge wire. The circuit also includes a 100nF capacitor for resonance, with a 10k resistor connected to the base of the transistor, and a red LED placed between the base and emitter pins for regulation.
To enhance the performance, I added an extra copper coil from a synchronous motor in parallel with the existing secondary coil. This modification resulted in a significant improvement, doubling the arc length to around 0.2-0.4 cm, indicating better energy transfer.
This experiment shows how the addition of extra inductive components can improve the Tesla coil’s performance, offering greater insights into resonance tuning and high-voltage generation.
