Question

assume the electrons are flowing2 years continueously in standard copper wire.if the free electrons are continuesly flowing freom one place to another place after how the copper wire having free electron in the starting point .please explain deeply not briefly ?

Answer 1

If i understand the question, the source for the electron flow, is not the copper wire, but either a battery or a generator, the copper wire is a conductor and is just the medium that provides the path for electron flow, after 2 years provided the battery has not completely discharged or the generator is still functioning, electrons will continue to flow. However, if the battery becomes completely discharged,flow will cease. The flow is not depleting the electrons that make up the copper wire, but being provided by a electromotive force EMF.
