Physics Semiconductor Electronics NEET Previous Year Question MCQ (Single Correct)

In this question, statement of Assertion is followed by a statement of Reason.

Assertion: In common base configuration, the current gain of the transistor is less than unity.

Reason: The collector terminal is reverse biased for amplification. [2006]

If both assertion and reason are true and the reason is the correct explanation of the assertion

If both assertion and reason are true but the reason is not the correct explanation of the assertion.

If assertion is true statement but reason is false.

If both assertion and reason are false statements.

The correct answer is:

CHECK THE SOLUTION.

In common base configuration input is applied between emitter and base and output is taken between collector and base. In this connection the base of the transistor is made common to both input and output terminals.

For amplification, emitter terminal is forward biased and collector terminal is reverse biased. In this configuration, the current gain is ratio of change in collector current to the change in emitter current at constant collector base voltage .
