Electrical Pioneer is a term used to describe three influential scientists in the field of electricity: Nikola Tesla, Georg Ohm, and Alessandro Volta. Tesla was a Serbian-American inventor and engineer who made groundbreaking contributions to the design of the modern alternating current (AC) electricity supply system. Ohm was a German physicist who formulated Ohm's law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points. Volta was an Italian physicist who invented the first electrical battery. Alessandro Volta was his full name. All three of these scientists were pioneers in the field of electricity and have had a lasting impact on the world.
