Thanks for the replies! This debate is actually for a real life application. We're just building a caveman circuit; all it is is a coil being shorted out to heat a wick. I'm thinking of using copper bars to connect the terminals of the battery (don't worry, they're rated high enough for this)...

Let's say the wires are magnified or we have the equipment to measure very precisely, would the resistance of the top wire be less? I believe it is less, but my friend keeps using a water pipe as an analogy and that the thin wire (pipe) will limit the flow of electrons. I say that this isn't the...

Homework Statement There are two wires: Wire one looks like --=========-- Wire two looks like --------------- Do they have the same resistance? So this isn't actually one of my homework problems, but I'm just debating this with a friend and neither of us can come to an agreement. So...
