Electronic Devices question

2023 · 25 Jan · Shift 1 · Q50

JEE MainPhysicsElectronic DevicesMCQ+4 / −1
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 ∣Vz∣>±v≥∣v0∣\mathrm{|{V_z}| \gt \pm v \ge |{v_0}|}∣Vz​∣>±v≥∣v0​∣ where v0\mathrm{v_0}v0​ is the threshold voltage and Vz\mathrm{V_z}Vz​ is the breakdown voltage. In the light of the above statements, choose the correct answer from the options given below
  1. A
    Both A and R are true but R is NOT the correct explanation of A
  2. B
    A is true but R is false
  3. C
    Both A and R are true and R is the correct explanation of A
  4. D
    A is false but R is true
