The elementary charge, uisually denotit as e, is the electric charge carried bi a single proton, or equivalently, the negation (opposite) o the electric charge carried bi a single electron. This elementary charge is a fundamental pheesical constant. Tae avoid confusion ower its sign, e is sometimes cried the elementary positive charge. This charge haes a measured value o approximately Lua error in package.lua at line 80: module 'Module:Gapnum' not found. coulombs. In the cgs seestem, e is Lua error in package.lua at line 80: module 'Module:Gapnum' not found..
