The knee voltage of a crystal diode is approximately equal to ________________?
Correct answer: D. barrier potential
- A. applied voltage
- B. breakdown voltage
- C. forward voltage
- D. barrier potential
Explanation
The knee voltage is the approximate forward voltage at which diode current begins to rise sharply, so it is associated with the barrier potential of the junction. Breakdown voltage belongs to reverse-bias operation and is not the knee voltage in this context.
