Question

When you stop flowing current through the metal, what will happen?​

Answer 1

Answer:

I know that current is produced due to potential difference which makes the free valence electrons being passed on in a copper wire(or am i wrong, plz crt me if so). Each copper atom provides a single free electron. When a voltage is connected across a piece of copper, it pushes the free electrons so that they flow through the metal – that's an electric current.
