Physics Question from JEE Main 2023 · 25 January, Shift 1

Given below are two statements: one is labeled as Assertion AA and the other is labeled as Reason RR.

Assertion AA: Photodiodes are used in forward bias usually for measuring the light intensity. Reason RR: For a pp-nn junction diode, at applied voltage VV the current in the forward bias is more than the current in the reverse bias for Vz>±V0|V_z| > \pm V_0|, where V0V_0 is the threshold voltage and VzV_z is the breakdown voltage.

Options:

  • A

    Both AA and RR are true and RR is the correct explanation of AA

  • B

    Both AA and RR are true but RR is NOT the correct explanation of AA

  • C

    AA is false but RR is true

  • D

    AA is true but RR is false
