    Ohm's Law 2
    From: Doug Royer
    Date: 2004 Oct 15, 18:10 -0700

    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.
