I have a simple series circuit, with a 9V power supply, and a 1 ohm resistor. If I place to identical fuses in series on opposite sides of the resistor that are rated for <9A, which fuse will blow first? I am essentially asking if current flows identically through all points in a wire the instant the circuit is closed, or if there is an instant at "the speed of light (electrons)" where current flows only in the high electron side of the wire. Basically I'm thinking (if I revert to the water metaphor), there is a hose and I can either open the supply to with it empty hose that needs to have water passed through it, or I canopen it with an already filled hose which will instantly start passing water though the free end. Hopefully this isn't too vague..
