Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: electro- comb. form, dynamometer n.

Etymology: < electro- comb. form + dynamometer n., after German Elektrodynamometer ( W. E. Weber Elektrodynamische Maasbestimmungen (1846) 15).

1. An electrodynamic instrument for measuring electric current or electric power, esp. one consisting of an arrangement of current-carrying coils.

It consists of two coils of fine wire, the smaller of which is suspended within the other by a bifilar suspension, so that their centres coincide and their axes are at right angles.
