“Physics and Our Universe: How It All Works” S:1 E:30 Electric Potential

S:1 E:30 Electric Potential Jolt your understanding of electric potential difference, or voltage. A volt is one joule of work or energy per coulomb of charge. Survey the characteristics of voltage: from batteries, to Van de Graaff generators, to thunderstorms, which discharge lightning across a potential difference of millions of volts.
