Semiconducting Devices Question 13
Question: Assertion : In transistor common emitter mode as an amplifier is preferred over common base mode. Reason : In common emitter mode the input signal is connected in series with the voltage applied to the base emitter function.
Options:
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.
