WebMar 19, 2024 · Transistors may be used as switching elements to control DC power to a load. The switched (controlled) current goes between emitter and collector; the controlling current goes between emitter and base. When a transistor has zero current through it, it is said to be in a state of cutoff (fully nonconducting). WebApr 10, 2024 · The invention of transistor revolutionized the electronics industry. The transistor is a three-terminal current control device, that can be used to create complex electronic circuits. Even though there are other types of transistors, Bipolar Junction Transistors (BJT) are still popular and used everywhere.
