I did a google search that explain that the speed of an electrons, if it is not disturbed by anything, is about 2,200 kilometers per second. However the length the electrons travel in an electric circuit is different.
Electrons are moving VERY fast. However, they don't have a high drift velocity in a circuit. Why? Is it because every time they advance a little bit they collide with an atom? Or is it because the electric field in a circuit is not strong enough so the electrons don't get pushed enough?
But the magnetic field makes the electrons MOVE... how is it not kinetic energy? What is this energy?
If it is potential energy, could you help me conceptualize how it is potential energy?
Hi,
In a current generated by an alternator, can we really say that there is a potential difference like in a battery?
The magnetic field exerts a force on the electrons which makes them move. We can calculate the work done to the electrons in joules, and we can divide this energy by the...
This is something that I have trouble understanding. The thing that makes electrons flow in a battery circuit is the accumulation of electrons in one side and the lack in the other side. This makes the electrons push each other, there isn't any field involved there? The general movement of...
The last equation of the text says that to have a voltage, the battery MUST do work on a charge at some point. Your text says that the battery DOES work on the charge, but not how. I'm still a little bit confused...
There is an explanation of how a battery works that says that in a battery circuit, the electrons do a complete loop and, given enough time, they can return to their starting point. This theory says that when the electrons arrive in the positive terminal and they lost all of their potential...
