elektronladning
Elektronladning refers to the electric charge carried by a single electron. It is a fundamental property of matter and a quantized value, meaning it exists in discrete units. The symbol for the elementary charge is commonly denoted as 'e'. While the charge of an electron is negative, the magnitude of the charge of a single electron is equal to the magnitude of the charge of a single proton, which is positive.
The value of the elementary charge was first precisely measured by Robert Millikan in his oil-drop experiment
The concept of electron charge is central to understanding electricity, electromagnetism, and the behavior of atoms.
