Kirchoff's Law With Battery Only

  1. Jul 28, 2011 #1
    Hello,
    If one had a resistance free wire and a battery with no internal resistance, how would Kirchoff's law be applied if the terminals of the battery were connected by the wire? Is this even an appropriate question? I know/believe current would be at infinity. I am still trying to fully understand voltage, but because it is a conservative electric field, wouldn't the equation still be equal to zero?

    Thank you

    It is not an appropriate question. Anything that generates infinite current is non-physical.

    Any real voltage source has a finite internal resistance. So if you connect it to a superconducting wire, the current is determined by the finite internal resistance of the voltage source.
