Note that this isn't a homework problem, just a question the concept.
Let's take this quick circuit I drew up just now in MS paint. There are three different currents, one for the top, middle, and bottom branches. The bottom two branches have a voltage source on each, and there's a resistor in the top branch. So we have some set values for the current in each branch, found by using Kirchoff's rules.
Now I add an extra bit of wire at the top, around the resistor:
Is this what a short circuit is? What happens to the current at the top? Does it go completely around the resistor and through the added wire? Or does some of it still go through the resistor? Certainly something would have to change in order to find the currents again, using Kirchoff's rules.
People often say that current takes the path of least resistance, but it feels like that's not completely true.
