Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as
Assertion: A p-n junction with reverse bias can be used as a photo-diode to measure light intensity. Reason: In a reverse bias condition the current is small but it is more sensitive to change in incident light intensity.A) If both assertion and reason are true and the reason is the correct explanation of assertion.
B) If both assertion and reason are true but the reason is not the correct explanation of the assertion.
C) If assertion is true statement but reason is false.
D) If both assertion and reason are false.
Correct Answer: A
Solution :
Photo-diode is a reverse biased p-n junction diode as shown in figure. At the p-n junction there exists a junction field which atYou need to login to perform this action.
