Question

What causes electric current in a wire

Answer 1

Answer:

The difference in potential at two points in a wire causes electric current in a wire.

Explanation:

Electric Current:

The flow of Electric charges is called Electric Current.

An electric current is said to exist when there is a net flow of electric charge through a region. In electric circuits this charge is often carried by electrons moving through a wire.

Electrons move in a wire from lower potential to higher potential because, positive charge attracts the negative charge and causes it to move towards itself.
