The arrow in the symbol of a transistor indicates the direction of____________?
Correct answer: C. hole current in the emitter
- A. electron current in the emitter
- B. electron current in the collector
- C. hole current in the emitter
- D. donor ion current
Explanation
The transistor arrow follows the direction of conventional emitter current, conventionally associated with hole-current direction. It distinguishes NPN, whose arrow points out, from PNP, whose arrow points in.
