ديباي

Also known as D

The debye ( , ; symbol: D) is a CGS unit (a non-SI metric unit) of electric dipole moment named in honour of the physicist Peter J. W. Debye. Likely the earliest recommendation for the Debye as a unit was in the Physikalisch-chemisches Taschenbuch (physical chemistry handbook) written by Carl Drucker and Erich Proskauer in early 1932. It is defined as statcoulomb-centimetres. Historically the debye was defined as the dipole moment resulting from two charges of opposite sign but an equal magnitude of 10−10 statcoulomb (generally called e.s.u. (electrostatic unit) in older scienti
