A more elaborate question " With my previous knowledge I am aware that a wire possesses a sea of electrons ( free electrons) and the flow of those electrons is called current . The energy to flow is given by the battery converting chemical to electrical energy " But after seeing this video, it rather shows battery as a more of a source of electrons flowing from the negative to the positive terminal .
My view : After chemical reaction in the battery it produces electrons , those electrons flow through the wire repelling other free electrons present in the conductor(wire) forming a chain of electrons repelling and flowing through the positive terminal . *This energy or electrical energy is provided by the electrons formed during the chemical reaction at the negative terminal which repel other electrons in the wire being the driving force and source of the electrons
Is this the correct theory for how a circuit with a battery works? If not , would be helpful if you could correct me.
