单词 back e.m.f.
释义
back e.m.f.

Physics
  • An electromotive force that opposes the main current flow in a circuit. For example, when the coils of the armature in an electric motor are rotated a back e.m.f is generated in these coils by their interaction with the field magnet (see inductance). Also, in an electric cell, polarization causes a back e.m.f. to be set up, in this case by chemical means.
