Hey guys, I'm going to university next year to complete a degree in electronics engineering and I'm hoping to get a head start.
Ok I've attempted to read several online materials to try and create a mental model of what occurs in an electronic circuit. Let's assume its a basic circuit with a battery, copper wires, and a load. And I'll also assume non-conventional current i.e. electron flow from negative to positive terminal inside battery. Ok so beginning from the battery, my first question arises, I've read that inside the battery there is an electric field directed from the negative to the positive terminal, is there a build up of electrons at the positive terminal of the battery to induce this field?
From there work is done on the electrons from the chemical reactions inside the battery to push electrons against this electric field gaining electric potential in the process, so once the electrons leave the positive terminal of the battery, is there another electric field created in the circuit to push the electrons around the circuit whilst reducing electric potential eventually returning to the negative terminal?
I'm assuming there is, if so, what is creating this electric field?
Thanks in advance
