In the transistor schematic symbol, the arrow______________?
Correct answer: A. is located on the emitter
- A. is located on the emitter
- B. is located on the base
- C. is locate on the collector
- D. points form north to south
Explanation
The arrow in a transistor symbol is placed on the emitter and shows the direction of conventional current, with NPN pointing out and PNP pointing in. The likely mistake is choosing the base because it is the central terminal, but the base has no arrow.

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.
