Chapter 4: Problem 1

The three terminals of a bipolar junction transistor are called (a) \(p, n, p\) (b) \(R, p, n\) (c) input output ground (d) base, emitter, collector

Short Answer

Expert verified
The correct names of the three terminals of a bipolar junction transistor are base, emitter, and collector, as given in option (d). These terminals are connected to the emitter, base, and collector regions in both NPN and PNP types of BJTs, which control the flow of charge carriers (electrons and holes) through the transistor.

Step by step solution

01

Identifying different types of bipolar junction transistors

A bipolar junction transistor (BJT) is a type of transistor that uses both electrons and holes as charge carriers. There are two types of BJTs: NPN and PNP. NPN transistors have two n-type semiconductor layers sandwiching a p-type layer, whereas PNP transistors have two p-type layers with a central n-type layer. The three layers form the emitter, base, and collector regions in both types of BJTs.
02

Identifying the terminals of a BJT

Each type of BJT consists of three terminals that are connected to the three different layers (emitter, base, and collector). Here is the name of these terminals: 1. Emitter: The terminal that emits charge carriers (either electrons or holes). 2. Base: The terminal that controls the flow of charge carriers between the emitter and collector. 3. Collector: The terminal that collects the charge carriers emitted from the emitter.
03

Choosing the correct answer

Looking at the given options, we can see that option (d) base, emitter, collector is the correct answer as it matches the names of the terminals of a bipolar junction transistor. The other options do not accurately represent the three terminals of a BJT.
