Key Terminology
-
ESU of charge
-
The electrostatic unit of charge in the Gaussian CGS system, representing charge measured by forces between point charges in vacuum.
-
Millicoulomb [mC]
-
An SI unit of electric charge equal to one-thousandth of a coulomb, used for quantifying charge transfer or storage at practical engineering scales.
