Answer 1

Answer:

Ben Franklin nvented convintional current theory​ in 1750

Answer 2

Explanation:

The idea that electricity flows from the positive terminal to the negative goes all the way back to one of America's Founding Fathers, Benjamin Franklin. In Ben Franklin's time, there were no batteries, and no knowledge of the existence of electrons. He discovered that when certain hard, smooth substances were rubbed against cloth-like fibrous surfaces, an attractive force was created between the two.

If the bodies were brought close to each other, the attractive force would discharge between them as a spark. Franklin imagined that a special kind of fluid called "electric fluid" existed in the bodies, and would move from one body to another when they were rubbed together.

In order to record his experiments for posterity he needed to give names to the new ideas and objects he was dealing with. He imagined that the hard and shiny things - glass, wax, amber and sulfur - had more electric fluid than the materials with fibers on the surface - wool, dry cloth, or fur. He concluded that the electric fluid moved from a place of plenty (he called it "positive") to a place of deficit ("negative"). After Ben Franklin wrote about this idea in 1750, everyone adopted it because he was a respected pioneer in the field.
