Voltage, electric potential difference, electric pressure or electric tension (denoted ∆V or ∆U) is the difference in electric potential energy between two points per unit electric charge. The voltage between two points is equal to the work done per unit of charge against a static electric field to move the charge between two points and is measured in units of volts (a joule per coulomb).
Voltage can be caused by static electric fields, by electric current through a magnetic field, by time-varying magnetic fields, or some combination of these three. A voltmeter can be used to measure the voltage (or potential difference) between two points in a system; often a common reference potential such as the ground of the system is used as one of the points. A voltage may represent either a source of energy (electromotive force), or lost, used, or stored energy (potential drop).
Given two points in space, A and B, voltage is the difference in electric potential between those two points. From the definition of electric potential it follows that:

Plot: After street vigilante Kelly Keane aka LYNX wins a televised audition to become the latest member of THE POWERGIRLS, she finds them to be rather less than heroic; more obsessed with how they look and their popularity than actually saving lives. Their crafty manager, Ben Kline has created them to be the Spice Girls of the superhero world but when evil MISS DEMEANOR attacks London, the girls must work together and become the true superhero team everyone thinks they are.

Plot: After Peter Frisk is locked up in a rehabilitation centre for supervillains, he emerges a changed man, though not exactly by choice. He's been fitted with a shock collar that doles out hearty bursts of electricity when it detects negativity from the wearer. His twelve step process (and his general tolerance for physical pain) is put to the test when faced with his mother's nagging, and his little sister Shelly's surgical antagonisms. Peter's patience is stretched even further when his nemesis (the dashing moralist Captain Paragon) tightens the grip of his justice on a city just trying to get by. ...Maybe what this city needs is just a little bit of villainy after all.

i could watch you for a lifetime, you're my favorite movie
a thousand endings, you mean everything to me
i never know what's coming, forever fascinated
hope you don't stop running, to me 'cause i'll always be waiting
you gotta believe in the voltage that lives inside us.
so lets buckle up and break our walls down.
