By combining 49 of them he’s put together a soda bicarb diode steering circuit for a 7-segment display capable of showing the digits 0 to 9. He takes the idea for his diode from electrolytic ...

Transistors are the fundamental building blocks behind today's electronic revolution, powering everything from smartphones to ...

The red LED provides visual indication of the current flowing through the resistor-zener-diode circuit. The higher the current, the brighter the LED will light. You can omit this LED if you don’t need ...

In essence, the four-layer diode was the first integrated circuit since it did the work of two transistors, two resistors, and a diode -- all in a single crystal. Unfortunately, they were so ...

A tunnel diode amplifier circuit. Chetvorno [CC0] Particularly if your textbook is a little older, you may find a short section talking about the tunnel diode. There will be an odd-looking circuit ...
