Firstly a battery causes an accumulation of electrons in the negative terminal right? Hence the positive terminal is relatively positive and so an electric field is produced.
This electric field will cause electrons to move from the negative terminal to the positive terminal and on doing so the electrical potential would decrease and the change in electrical potential is what’s called voltage.
Now I always think of electrons moving in a field as a ball being dropped from a height so this potential energy is converted into another kind of energy which is supplied to components.
After an electron supplies energy to a component how does it continue to have no energy? Wouldn’t the electric field accelerate the electron so that the electron would gain more energy even after supplying energy to a component?
