The elementary charge, usually denoted by e, is a fundamental physical constant, defined as the electric charge carried by a single proton or, equivalently, the magnitude of the negative electric charge carried by a single electron, which has charge −1 e.

What Does Elementary Charge Mean? An elementary charge is the magnitude of electric charge associated with a single electron. Similar to time, length or mass, the elementary charge is a fundamental measurement of a fundamental physical constant. The coulomb is the unit of elementary charge in the International System of Units.
The elementary charge, usually denoted by e, is the electric charge carried by a single proton or, equivalently, the magnitude of the negative electric charge carried by a single electron, which has charge −1 e. This elementary charge is a fundamental physical constant. e = 1.602176487 x 10-19C.
The meaning of ELEMENTARY CHARGE is a fundamental constant that is the smallest known quantity of electricity and that has a value (either positive or negative) of 1.602176634 ×10-19 coulombs.
It is the electric charge carried by a single proton or, equivalently, the magnitude of the electric charge carried by a single electron, which has charge −e. The numerical value of the elementary charge, symbol e , is defined to be exactly 1.602 176 634 × 10 −19 when expressed in the unit coulomb , symbol C, or s A.
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.
An electron can’t be broken into smaller pieces, so charge always changes in multiples of the elementary charge. This property of electrons means that charge is quantized and the charge on any object must be an integer multiple of the elementary charge. An object’s charge can be 0 e, 1 e, − 1 e, 2 e , etc., but not 1 4 e, 1 2 e , etc. Learn more.
