Chapter 4: Problem 2

In a pnp transistor, the \(p\) regions are (a) base and emitter (b) base and collector (c) emitter and collector

Short Answer

Expert verified
In a pnp transistor, the p-type regions are the base and emitter. Hence, the correct answer is (a) base and emitter.

Step by step solution

01

Understanding pnp transistor structure

A pnp transistor is a type of bipolar junction transistor (BJT) and consists of three layers of semiconductor material - one n-type and two p-type layers. The two p-type layers are separated by an n-type layer in the middle, giving us the name "pnp." The three regions formed by these layers are base (B), collector (C), and emitter (E).
02

Identifying p-type regions in pnp transistor

In a pnp transistor, we have two p-type regions and one n-type region. These regions are base, collector, and emitter. Since we are looking for p-type regions, we know that the base and either the collector or the emitter are p-type regions.
03

Choose the correct option

Now that we have identified the p-type regions in a pnp transistor, let's look at the given options: (a) base and emitter (b) base and collector (c) emitter and collector We have identified the p-type regions as base and either collector or emitter in Step 2. Comparing with the given options, we can conclude that the correct option is (a) base and emitter.
