- Electric Charge
Electric charge is matter experiencing force in an electromagnetic field. Electric charge can be felt far away (called an electric field). In fact there is no limit, but it does get weaker the further we go. Charge is measured in Coulombs (C) and can be any multiple of the elementary charge (e), such as 0, +1e, -1e, +2e, etc.
If voltage, (V) equals Joules per Coulombs (V = J/C) and Amperes (I) equals charge (coulombs) per second (A = Q/t), then we can define electrical power (P) as being the totality of these two quantities. This is because electrical power can also equal voltage times amperes, that is: P = V*I.

Learn what electric charge is, how to measure it, and how it behaves. Find out the difference between positive and negative charges, the properties of charge, and the methods of charging by friction, conduction, and induction.
16 Ιαν 2023 · The e is a non-SI unit of charge. As stated 1e = 1.60 ×10−19C. In units of e, the charge of a proton is 1e (exactly) and the charge of an electron is −1e. For some reason, there is a tendency among humans to interpret the fact that the unit the e is equivalent to 1.60 ×10−19C to mean that 1e equals −1.60 ×10−19C.
