Dimensions of integral of voltage curve

AI Thread Summary
The discussion centers on the physical dimensions of the integral of voltage with respect to time. It notes that electrical potential is defined as energy per unit charge, expressed in joules per coulomb. When integrating voltage over time, the resulting units are joule-seconds per coulomb, which can be interpreted as action per charge. The participants express uncertainty about the application or nomenclature of this unit in biological contexts. Overall, the conversation highlights a gap in understanding the relevance of these units in biology.

I recently answered several questions in the biology forum regarding integrating over the change of voltage with respect to time. Although it wasn't part of the posters' question, I'm not sure about the physical dimensions of this integral. Electrical potential can be expressed as energy per unit charge or joules per coulomb. If you integrate over time you get the units joule-seconds per coulomb or action/charge. I'm not familiar with of the use of this unit in biology. Does it have a name?

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...

Thread 'Why measure the speed of light in one direction?'

It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
