P-N Junction Diode
A diode and resistance are connected as shown in figures.
Out of the following statements, which one is true?
Diode in
A) fig (1) and fig (2) are both forward biased.
B) fig (1) and fig (2) are both reverse biased.
C) fig (1) is forward biased and in fig (2) is reverse biased.
D) fig (1) is reverse biased and in fig (2) is forward biased.
Show answer and solution
Answer: (a)
- Forward bias needs anode potential > cathode-side potential.
- Fig. 1: anode , other end ; , so reverse biased.
- Fig. 2: anode , other end ; , so forward biased.
- Statement D is true, so the answer is (a) D.
