A Tesla coil is an electrical resonant transformer circuit invented by Nikola Tesla around 1891. It is used to produce high-voltage, low-current, high-frequency alternating-current electricity. Here's ...
How It Works This project demonstrates a push-pull switching circuit using complementary BJT transistors to alternately drive two LEDs. The circuit uses: 2N2222A (NPN transistor) 2N5401 (PNP ...
