Transistor DefinitionA transistor is defined as a semiconductor device with three terminals (Emitter, Base, and Collector) and two junctions (Base-Emitter and Base-Collector).Transistor is a semiconductor device with three terminals: Emitter (E), Base (B), and Collector (C). It has two junctions: Base-Emitter (BE) and Base-Collector (BC). Transistors operate in three regions: cutoff (fully off), active (amplifying), and saturation (fully on).When transistors operate in the active region, they ac
