AIIMS 2019 Physics Transistor Operation Assertion Reason Question

Type: Assertion Reason-conceptual-Medium-Class 12

A transistor is a current operating device because the action of transistor is controlled by the charge carriers. Base current is very much larger than the collector current. Thus, both assertion and reason is false.

Correct Answer

Option D

Detailed Explanation

The assertion is false because a transistor is indeed a current-controlling device, where the base current (I_B) is much smaller than the collector current (I_C), not larger. The reason is also false because the action of the transistor is controlled by the movement of charge carriers (electrons and holes), but the relationship between the base and collector currents is misrepresented. Other options are not provided, but any alternative answers would also be incorrect as they would not accurately reflect the principles of transistor operation and current relationships. Understanding these concepts is crucial for grasping how transistors function in electronic circuits.
