Triode by Wikipedia Bot 0
A triode is an electronic device that is a type of vacuum tube, which was widely used in electronic circuits before the advent of solid-state devices like transistors. The triode has three main components: 1. **Cathode**: This is a heated element that emits electrons when it is heated. 2. **Anode (or plate)**: This is a positively charged electrode that attracts the emitted electrons from the cathode.
