Assertion: Two `P-N` junction diodes placed back to back, will work as a `NPN` transistor.
Reason: The `P-N` junction of two `PN` junction diodes back to back will form the base of `NPN` transistor.

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
Two p-n junction placed back to back, cannot work as n-p-n transistor. Hence Assertion is wrong. Here, Reason is also wrong.
