How much energy is gained by an electron in a battery?

AI Thread Summary
The energy gained by an electron in a battery varies depending on the battery's voltage. This energy can be expressed in electron volts (eV), where the energy is calculated as the charge of the electron multiplied by the battery's voltage. The relationship between voltage and energy is defined by the equation 1 volt = 1 joule/coulomb. Therefore, for a given voltage, the energy gained by an electron is directly proportional to that voltage. Understanding this relationship is crucial for evaluating the energy output of different types of batteries.

Depends on the battery. Batteries range from tiny watch batteries to car batteries to even larger specialized ones.

The energy gained is proportional to the voltage of the battery; instead of joules think of electron volts (eV).
 
The enrgy is the charge of the electron times the voltage of the battery.
 
Note that in terms of units, 1 volt = 1 joule / coulomb, so 1 volt * 1 coulomb = 1 joule.

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...
