Hi,
I am learning about emf. I understand that it is the Work done per unit charge to move it around a circuit.
However, reading my book, I got a bit confused. It started to explain a bit about how a battery functions. From what I understand, chemical reactions do work in order to force electrons to concentrate on the negative side of the battery. This, thereby, establishes an electric field.
So, the work in the definition of an emf is the work described above? Electrons from the negative terminal of the battery then flow through the wires, repelling the delocalized electrons?
I am confused!
Thanks in advance.
