STANDARD Physics Diode Characteristics MCQ Question
Type: MCQ-numerical-Medium
The V-I characteristic of a silicon diode is shown in figure. The resistance of the diode at I_D = 15 mA is
A
5 Ω
B
10 Ω
C
2 Ω
D
20 Ω
Correct Answer
Option B
Detailed Explanation
In the figure, at I = 20 mA, V = 0.8 V and at I = 10 mA, V = 0.7 V. The resistance can be calculated using the change in voltage divided by the change in current.
