The CORRECT symbol of a n-p-n transistor is(Note: Where 'E', 'B' and 'C' have their usual meaning.)
Correct answer: A. Option A
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
The correct symbol of a n-p-n transistor is Emitter-Base-Collector, where the arrow points in the direction of conventional current flow. Option A is correct because it follows this order and convention. Options B, C, and D are incorrect as they do not accurately represent the symbol of a n-p-n transistor.

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.
