Which is true about forward voltage drop in a diode?
It is lower in some diode types than in others✓Bonne réponse
It is proportional to peak inverse voltage
It indicates that the diode is defective
It has no impact on the voltage delivered to the load
Explication
Forward voltage drop is set by the junction material, so it differs by diode type: roughly 0.3 V for germanium, 0.7 V for silicon, and more for LEDs and some other devices. It is a normal property, not a sign of a defect, and it does reduce the voltage reaching the load.
