The current in a Zener diode is limited by _______________?
Correct answer: C. Both (A) and (B)
- A. External resistance
- B. Power dissipation
- C. Both (A) and (B)
- D. None of the above
Explanation
The series or external resistance limits the current entering the Zener, while the diode's power-dissipation rating limits the maximum safe current. Therefore both factors restrict Zener current.
