The potential (with respect to infinity) of a point charge is then: If you have more than one point charge, the total potential at some location is just the sum of the electric potentials due to ...

Historically, we call this change in electric potential across the battery the emf which usually stands for ElectroMotive Force. But clearly, it isn't a force since it has units of volts.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

On December 1, 2014, the team measured a thundercloud with an electric potential of 1.3 billion volts, or 1.3 gigavolts -- the most powerful electric storm ever measured.

Preliminary data hint at bioelectricity’s potential. By tweaking cellular electric signals with the right tools, scientists may one day be able to heal wounds or spur lost tissues to regenerate.

Lift off The Endurance rocket ship launches from Ny-Ålesund, Svalbard. (Courtesy: Andøya Space/Leif Jonny Eilertsen) A drop in electric potential of just 0.55 V measured at altitudes of between ...

An electric discharge occurs when ion channels are opened, allowing the ions to flow back into the electrocyte. Given that an electric eel has thousands of electrocytes stacked in series, this animal ...
