Question

why only free electrons responsible to flow,not all​

Answer 1

Answer:

electrons can move in response to an applied electric field. To be honest, a free electron is no more responsible for flow of current than a train is responsible for travelling along electrified rails. The thing that is responsible, in both cases, is a potential difference being maintained by electrical energy....
