Hello,
I'm trying to get an image of a reasonably detailed model of electric current of standard close circuit with an electrochemical battery into in my head, well to an A level standard, I’m a fairly visual learner so image descriptions help :)
I’m also very new to physics, I’ll try and describe this the best I can, but sorry if it’s confused.
From my reading of the physicsclassroom.com and internet,
I’ve read the electric field is generated by the PE difference across the two terminals and it is this which causes the movement of electrons around the circuit, but I’ve also read that it’s the electron movement that generates the field.
But what comes first? When the wire is connect to battery does the field appear and force (just as two like charges repel) the delocalized electrons to move with the field? From high to low PE.
I think my understand might be wrong as this seems a bit like the chicken and the egg to me, the field moves the electrons, the electrons create the field, which comes first?
1) Where is this field coming from, and at what point in time upon making the connection does it appear.
2) How does the field know to surround the wire if it’s not directly related physical metal
3) Is the field around the wire or inside the wire.
4) How does it relate to the magnetic field that surrounds the wire, or is this a separate phenomenon? (the books make it sound like separate thing) Is it truly the field that moves the electrons?
