"\\(\\textbf{Elementary Charge}, usually denoted as \\(e\\), 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 \\(1.602176634 \\times 10^{-19} coulombs\\). In the cgs system, \\(e\\) is \\(4.80320471257026372 \\times 10^{-10} statcoulombs\\)."^^ .
