With the help of the German inventor Otto von Guericke, who discovered that vacuums can be formed, Gilbert was able to produce a machine that created static energy; the first ever electric generator. ... So this is where the first DC electricity supply was discovered.

How was direct current invented?

Starting in the late 1880s, Thomas Edison and Nikola Tesla were embroiled in a battle now known as the War of the Currents. Edison developed direct current -- current that runs continually in a single direction, like in a battery or a fuel cell.

Who discovered DC and AC current?

Both AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically.
