The forward current as compared to reverse current, while passing through a p-n junction is/ are alwaysI. lessII. moreIII. equal
Correct answer: D. II and III.
- A. I only.
- B. II only.
- C. I and III.
- D. II and III.
Explanation
In a p-n junction, the forward current is typically more than the reverse current. This is due to the way the junction is formed, allowing for easier flow of current in one direction compared to the other. Option A, B, and C are incorrect as they do not accurately reflect the behavior of forward and reverse currents in a p-n junction.

About PN Junction
A PN junction forms when p type and n type semiconductor regions meet, creating a depletion layer and a potential barrier. The topic covers forward and reverse bias, diode current voltage characteristics, breakdown and rectification, while distinguishing an ordinary junction diode from a transistor formed from multiple junctions.
