What is the trouble with a silicon diode that measures a low value of resistance with the meter leads in both positions?
What is the trouble with a silicon diode that measures a low value of resistance with the meter leads in both positions?
- The diode is shorted to ground.
- The diode is working correctly.
- The diode is open.
- The diode is internally shorted. (correct)
Under normal conditions, a diode conducts current when it is:
Under normal conditions, a diode conducts current when it is:
- avalanched.
- forward-biased. (correct)
- saturated.
- reverse-biased.
As the forward current through a silicon diode increases, the internal resistance:
