    given this circuit...

    how could one reason that KVL applies to this (green) loop?

    Is it just zero? There is no current flowing between a and c?
    :confused:

    peterpants,

    There is no charge flowing through a and c because it is shorted. No voltage either.

    No voltage sources in the green loop, no voltage used in any of the circuit elements. KVL is 0 = 0

    if short circuited from A and C there is no current flowing. There can be Voltage, but no current .

    There cannot be voltage across a (ideal) short. Voltage implies current.

    The only voltage drop in this circuit will be across the 3 ohm resistor.

    Basically, don't try this circuit at home :)
