As I have read , charge is electrons , protons or neutrons.
Now , according to definition of current , current is the rate of flow of charge I.e flow of electrons. Then , I=Q/t . Unit of Q is coulomb & Q is charge. Right , so Coulomb is actually like the No of electrons flowing through the conductor. Also , $$Q=n*e$$
But there is another point in my book that charge on an electron = $$-1.6*10^{-19}$$. Now, this is confusing. Charge is electron , what does charge on an electron mean ? If charge is a like a numerical value , change on an electron means like there is some kind of energy the electron has. Is it that charge has two definitions?
Also , if charge is a number. What does it mean by negative symbol for charge ?
