Kirchhoff's Loop Rule: The directed sum of the electrical potential differences (voltage) around any closed circuit is zero. I'm an electron. I'm in a single loop series circuit with just a 5 volt battery and a resistor. The battery gives me a voltage boost of 5 volts and sends me on my way to the resistor. The resistor perfectly robs me of the 5 volts that I got from the battery. How, then, am I able to continue to flow? If my voltage gain is offset by an opposite and equal voltage loss, shouldn't I simply be stuck dead in the wire?
