WebDec 8, 2024 · A transistor works when the electrons and the holes start moving across the two junctions between the n-type and p-type silicon. Let's connect the transistor up to some power. Suppose we attach a small positive voltage to the base, make the emitter negatively charged, and make the collector positively charged. WebA thyristor is a solid-state semiconductor switching device. It is a bistable switch that operates in two stable states; non-conducting and conducting state. They are said to be an ideal switch but practically they have some limitations based on their characteristics. They are mostly used in high power circuits.
