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 'Inducing EMF Through a Coil: Understanding Flux'

Thank you for reading my post. I can understand why a change in magnetic flux through a conducting surface would induce an emf, but how does this work when inducing an emf through a coil? How does the flux through the empty space between the wires have an effect on the electrons in the wire itself? In the image below is a coil with a magnetic field going through the space between the wires but not necessarily through the wires themselves. Thank you.

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
