Why Electric Current Flows From Positive to Negative? (read the description as well)

In DC, electron flows from negative to positive. While the current flows the opposite. Why? This video will help you to understand the visualization of the concept. But actually, the key of the answer is the history of electricity. For short: electricity was discovered before the discovery of electron. The choice of which type of electricity is called "positive" and which "negative" was made around 1750 by Ben Franklin. Franklin studied static electricity, produced by rubbing glass, amber, sulfur etc. with fur or dry cloth. Franklin knew of two types of electric charge, depending on the material one rubbed. He thought that one kind signified a little excess of the "electric fluid" over the usual amount, and he called that "positive" electricity (marked by +), while the other kind was "negative" (marked -), signifying a slight deficiency. It is not known whether he tossed a coin before deciding to call the kind produced by rubbing glass "positive" and the other "resinous" type "negative" (rather than the other way around), but he might just as well have. It was noted in later experiments that when charged objects were brought into contact with the Earth through a conductor, a small charge flowed for a short time. When cells were invented, it was observed that a cell's carbon electrode behaved in a similar way to fur, and a silver electrode in a similar way to rubber. Thus, an "excess of electric fluid" (positive charge) appeared to be transferred from the positive carbon electrode (anode) to the negative silver electrode (cathode). The idea of positively charged flow remained in favour until the work of Joseph John Thomson (1856–1940). In a study of the flow of electricity through gases, (technology used today in neon signs), Thomson isolated a beam of negatively charged particles of much smaller mass than atoms. These originated at the negative terminal (cathode) in his gas tube and Thomson realised his cathode rays were composed of negatively charged electrons. This fundamental particle, the electron, was soon associated with all atoms and shown to be responsible for both static charging and electrical currents in metals. So, a century after that electrons were discovered and it was suddenly realized that in metal wires the electrons were the ones that carried the current, moving in exactly the opposite direction. Also, it was an excess of electrons which produced a negative electric charge. However, it was much too late to change Franklin's naming convention. https://pwg.gsfc.nasa.gov/Education/w... https://spark.iop.org/history-and-ele...
