Answer / sushil bagade

if we apply the E.M.F it create the P.D across the ckt and
due to that current is flow in short EMF have ability to
produce potantial difference and due to that electron flow
occure and that is nothing but current flow

Answer / pswin

Conductors have an abundance of free electrons which requires low pressure to move them from one atom to another, and establish a high current. This is the characteristic of conductors and that's why, current can flow through them.
