The forward voltage drop across a silicon diode is about _______________?
Correct answer: D. 0.7 V
- A. 2.5 V
- B. 3 V
- C. 10 V
- D. 0.7 V
Explanation
A silicon pn-junction diode has a forward knee voltage of approximately 0.7 V at ordinary operating currents. The corresponding approximate value for germanium is 0.3 V.
