What is the On Resistor of a Semiconductor Junction diode does?
Can you restate the question, or submit a schematic?
A junction diode obeys the resistance formula V=IR, as does every electric circuit. But it does not obey Ohm's law.
Its resistance is going to vary logarithmically with the current. http://people.seas.harvard.edu/~jon...de_characteristics/diode_characteristics.html . Ratch
The On resistor will use as a current limiter
It will keep the PN junction from overheating.
