EMU of Charge

EMU

Definition

EMU (Electromagnetic Unit) of charge is a unit in the CGS electromagnetic system, equal to 10 coulombs. It represents the electromagnetic unit of electric charge.

History/Origin

EMU of charge was part of the CGS electromagnetic system of units, defined based on electromagnetic principles rather than mechanical definitions.

Current Use

Historical unit rarely used in modern applications. The coulomb and other SI units have replaced the CGS electromagnetic system in most scientific and engineering work.
