WebApr 8, 2024 · A transistor is a semiconductor device, which is formed by fusing two junction diodes. When the anodes of the two diodes are fused, the transistor is called an n-p-n transistor. When the cathodes of the two diodes are fused, the transistor is called a p-n-p transistor. A transistor consists of three parts – a collector, an emitter and a base. WebThe npn transistor has two p-n junctions. One junction is formed between the emitter and the base. This junction is called emitter-base junction or emitter junction. The other junction is formed between the base and the collector. This junction is called collector-base junction or collector junction. Working of a npn transistor
