STANDARD Physics Diodes MCQ Question
Type: MCQ-conceptual-Medium
In figure, assuming the diodes to be ideal,
A
D₁ is forward biased and D₂ is reverse biased and hence current flows from A to B.
B
D₂ is forward biased and D₁ is reverse biased and hence no current flows from B to A and vice versa.
C
D₁ and D₂ are both forward biased and hence current flows from A to B.
D
D₁ and D₂ are both reverse biased and hence no current flows from A to B and vice versa.
Correct Answer
Option B
Detailed Explanation
Diode D₁ is reverse biased as p side is connected to negative potential and n side to ground. Diode D₂ is forward biased as p side is grounded and n side is at negative potential.
