Any two sources of electric current

Complete question is;

Name any two sources of electric current

Generators

Electrolytic cells

Explanation:

There are two main sources of electric current namely using generators and also by use of Electrolytic cells.

Generators make use of mechanical energy like water flowing through a dam or even the motion of a steam driven turbine to supply adequate voltage that's necessary to generate an electric current while Electrolytic cells make use of chemical energy to supply adequate voltage that's necessary produce electricity.
