After thinking about this for awhile I still don't know where you're coming from George. Here's what I'm thinking about this. Ex. # 1 2 plates of iron are fastened together so there is a large surface area touching each plate.A + potential is connected to 1 and the negative potential is connected to the 2nd. X amount of current will flow because of the low resistance. After a time corrosion builds up between the plates.The resistance between the 2 surfaces is now greater so less current will be able to flow with the same potential. Ohm's Law is valid. Ex. # 2 A 5 volt,1 watt zener diode is regulating the voltage in a circuit at its max knee current.The input voltage rises to the point that the wattage of the zener is exceeded thus destroying the junction. Ohm's Power Law is valid. Same with any other type PN junction. Will you please explain what you were getting at in your post reguarding this?Perhaps I misunderstand what you're trying to get across. This does have relavance to navigation because someone started the thread of lightning on the navigation list and there are plenty of responces along with George's statement.
