I watched a ted-ed (https://youtu.be/8EUy_82IChY#t=369), and the guy said “nobody knows what it is” so is it true? Do we not know what electricity is?
In: Physics
We definitely know what it is although it his highly debated whether or not electrons flow from a negative to positive or positive to negative. They flow from a live line (a cable with voltage) to a 0 volt or ground line for the reason mentioned above. We even know and can measure with cheap tools how many electrons flow through a single point in a line and how it is affected by a load of ohms or the electrical pressure of voltage. It’s highly controllable, measurable, and not terribly complicated.
