The base of a transistor is kept very thin and lightly doped as compared to the emitter and collector region so that

Options

A. most of the carriers pass to the collector when injected from the emitter
B. base current is high
C. recombination is increased in the bae region
D. flow across the base region is mainly because of majority carriers

Explanation

To understand why the base of a transistor is kept very thin and lightly doped compared to the emitter and collector regions, we can break down the explanation into a step-by-step solution.

### Step-by-Step Solution:

1. **Understanding the Structure of a Transistor**:
- A transistor consists of three regions: the emitter, base, and collector. In an NPN transistor, the emitter and collector are N-type (rich in electrons), while the base is P-type (rich in holes).

2. **Doping Levels**:
...
