Which is true about forward voltage drop in a diode?

  1. It is lower in some diode types than in othersپاسخ درست
  2. It is proportional to peak inverse voltage
  3. It indicates that the diode is defective
  4. It has no impact on the voltage delivered to the load

توضیح

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.
