Electric current has the following effect :

(i) Electric current can give rise to heating and lighting.

(ii) Electric current can convert a straight conductor into a temporary magnet.

Potential difference across the terminals of the cell is generated due to chemical reaction within the cell.

When the cell is connected to a conducting circuit element, the potential difference sets the charges inside the conductor in motion and produces an electric current.
