Assertion : When baseregion has larger w...

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.

Text Solution

Verified by Experts

The correct Answer is:
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.
