Question

In BJT, maximum current flows in which of the following?

• A. in the emitter
• B. in the collector
• C. in the base
• D. through CB junction

Answer 1

The correct option is A

in the emitter

Explanation for the correct answer:

Option A: in the emitter

1. BJT is a Bipolar Junction Transistor
2. As the name suggests, it has double poles.
3. Transistors consist of emitter, base and collector.
4. The doping in collector part is less than that in the emitter part and the base part.
5. Emitter current is given by the sum of current through the base and the collector.
6. Hence, highest current flows there.

Therefore, option A is the correct option.
