Question:
In a transistor:
In a transistor:
Show Hint
The base of a transistor is lightly doped to control the flow of charge carriers between the emitter and collector.
Updated On: Oct 8, 2025
- the emitter has the least concentration of impurity
- the collector has the least concentration of impurity
- the base has the least concentration of impurity
- all three regions have equal concentration of impurity
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding transistor structure.
In a transistor, the base region is lightly doped compared to the emitter and collector. This is done to allow for efficient control of the current flowing between the emitter and collector.
Step 2: Conclusion.
The correct answer is ( because the base of the transistor has the least concentration of impurity.
