Which one of the following is I-V curve of a junction diode?
Correct answer: B. Option B
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
Option B shows the I-V curve of a junction diode. This curve represents the behavior of the diode under both forward and reverse bias conditions.Under forward bias, the diode allows current to flow in the forward direction, with increasing current for increasing voltage until it reaches a certain voltage threshold called the forward voltage. Beyond this threshold, the current increases rapidly as the diode enters into saturation.Under reverse bias, the diode blocks the flow of current until the reverse voltage reaches a certain value called the breakdown voltage, beyond which the current increases rapidly.Therefore, option B is the correct choice for the I-V curve of a junction diode among the following diagrams.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
