Question
Which symbol in figure G7-1 represents an NPN junction transistor?
Answer Options
- A) Symbol 1
- B) Symbol 2
- C) Symbol 7
- D) Symbol 11
Correct Answer: B
Explanation
An NPN bipolar junction transistor (BJT) is the most common type of transistor used for amplification and switching. Its symbol is defined by the three terminals: collector, base, and emitter.
Symbol 2 represents the NPN junction transistor. The key identifying feature is the arrow on the emitter lead, which points out (Not Pointing iN) from the base, distinguishing it from the PNP transistor where the arrow points in. Correctly identifying this fundamental symbol is necessary for analyzing amplifier and logic circuits.
