Hi! I was looking at notes about voltage and resistance, and this question popped into my head. 1. The problem statement, all variables and given/known data If a certain length of wire ie)40m with an unknown resistance has a voltage of say 24V (random number) when hooked up to a battery, how does the voltage change throughout the circuit, or does it? ie) when a voltmeter is hooked up to a 10m segment of the wire anywhere on the wire, would the voltage increase or decrease? 2. Relevant equations P=IV R=pL/A 3. The attempt at a solution I'm not sure, but if i were to guess I would think of the wire as any other resistor and assuming resistance is constant throughout predict the same voltage? I'm probably completely off, but it's worth a shot. Thanks!
