Question

Given below are two statements ; one is labelled as Assertion A and the other is labelled as Reason R Assertion A: Photodiodes are used in forward bias usually for measuring the light intensity. Reason R: For a p-n junction diode. at applied voltage V the current in the forward bias is more than the current in the reverse bias for |V2|>± V ≥|V0| where V0 is the threshold voltage and V 2 is the breakdown voltage. In the light of the above statements, choose the correct answer from the options given below (A) A is true but R is false (B) A is false but R is true (C) Both A and R are true but R is NOT the correct explanation A (D) Both A and R are true and R is correct explanation A

Theory based
Photodiodes are operated in reverse bias condition.
For

P - N

junction current in forward bias (for

V \geq V_{0}

) is always greater than current in reverse bias

(

for

V \leq V_{Z}

) .
Hence Assertion if false but Reason is true

A is true but $R$ is false

A is false but $R$ is true

Both $A$ and $R$ are true but $R$ is NOT the correct explanation $A$

Both $A$ and $R$ are true and $R$ is correct explanation $A$

Theory based
Photodiodes are operated in reverse bias condition.
For $P - N$ junction current in forward bias (for $V \geq V_{0}$ ) is always greater than current in reverse bias $($ for $V \leq V_{Z}$ ) .
Hence Assertion if false but Reason is true

A is true but R is false

A is false but R is true

Both A and R are true but R is NOT the correct explanation A

Both A and R are true and R is correct explanation A

Theory based Photodiodes are operated in reverse bias condition. For P−N junction current in forward bias (for V≥V0​ ) is always greater than current in reverse bias ( for V≤VZ​ ) . Hence Assertion if false but Reason is true

A is true but $R$ is false

A is false but $R$ is true

Both $A$ and $R$ are true but $R$ is NOT the correct explanation $A$

Both $A$ and $R$ are true and $R$ is correct explanation $A$
