Question

If electrons are bound to atom by electromagnetic forces then how do they flow to cause electric current​

Answer 1

Answer:

it is the free electrons ( it is loosely bounded by nucleus) which flows.

Answer 2

Answer:

Electricity is the flow of electrons through a conductor, usually in the form of a wire, this flow is called an electric current. ... Breaking the atomic bond between an electron and its nucleus requires an input of energy which causes the electron to overcome the electromagnetic force constraining it and thus flow freely.
