The cause of electric current in a wire is that there is electron flow due to electrical attraction and repulsion.
What is Electric current?
The rate of flow of electric charge through a point is known as electric current. The electric current is nothing but the flow of electrons in general.
Consider a space, when electrons of charge (e) is flowing through the space in a given time interval t. Then,
I = e/t
here,
I is the electric current.
Moreover, there is a flow of electrons in a wire due to a potential difference existing at the circuit. Due to that, electrons always flow from high electric potential to low electric potential.
Thus, we can conclude that the cause of electric current in a wire is that there is electron flow due to electrical attraction and repulsion.
