Voltage drop along an idealized resistance-free wire in a circuit?


If you connected the positive terminal of a battery to the negative terminal to a battery with a wire with (hypothetically) no resistance, and are asked to give the voltage drop of a segment of wire in the circuit, how would you determine this?



Answer



Since you specified the wire, but not the battery, as being ideal, the result will be that there will be no voltage on the wire. Instead, the battery will be shorted out.
