Invention of DC Current

What is DC Current?

DC stands for Direct Current, even though it is frequently called “DC Current”. DC is characterized as a unidirectional flow of electric charge. In DC, the electrons move from an area of negative charge to an area of positive charge without heading in a different path....

Invention of DC Current

The DC was first presented by Italian physicist Alessandro Volta’s battery. Around then heading of the current was not presented. French physicist Ampere offers a perspective that ongoing travel in one heading from positive to negative. In the late 19th century, three creators, Nikola Tesla, George Westinghouse, and Thomas Edison battle picking the power system....
