Question

Assertion : When baseregion has larger width, the collector current increases.
Reason : : Electron hole combination in base result in increase of base current.
A. if both the Assertion and Reason are true and the Reason is the correct explanation of Assertion.
B. if both the Assertion and Reason are true but the reason in not a correct explanation of the Assertion.
C. if the Assertion is true but the Reason is false.
D. if both Assertion and Reason are false.

Answer 1

Correct Answer - D
When base region has larger width electron-hole combination in base region will increase, resulting increase in base current `I_(b)`. As `I_(e)=I_(b)+I_(c)`, so there will be decrease in collector current `I_(c)`. Thus, Assertion is false. Here Reason does not suppost the Assertion.
