elementary charge

The elementary charge, usually denoted as e or sometimes q, is the electric charge carried by a single proton, or equivalently, the negation (opposite) of the electric charge carried by a single electron. This elementary charge is a fundamental physical constant. To avoid confusion over its sign, e is sometimes called the elementary positive charge. This charge has a measured value of approximately 1.6021766208(98)×10−19 coulombs. In the cgs system, e is 4.80320425(10)×10−10 statcoulombs.

The magnitude of the elementary charge was first measured in Robert A. Millikan's noted oil drop experiment in 1909. https://en.wikipedia.org/wiki/Elementary_charge
