The "father of DC current" is generally considered to be **Thomas Edison**. He is credited with the development and promotion of direct current (DC) for electrical power distribution. Edison made significant contributions in the late 19th century by inventing the first commercially successful light bulb and setting up the first electrical power stations, which used DC to power homes and businesses.
However, it's worth noting that **Alessandro Volta** also made early contributions to the understanding of electricity and created the first chemical battery (the voltaic pile), which could produce a continuous electric current, but Edison's work in making DC a practical power source for wide-scale use is what earned him the "father" title.
