henries in Science
henry
  (hěn'rē)   
A SI derived unit of electrical inductance, especially of transformers and inductance coils. A current changing at the rate of one ampere per second in a circuit with an inductance of one henry induces an electromotive force of one volt.
Encyclopedia Article for henries

henry

unit of either self-inductance or mutual inductance, abbreviated h (or hy), and named for the American physicist Joseph Henry. One henry is the value of self-inductance in a closed circuit or coil in which one volt is produced by a variation of the inducing current of one ampere per second. One henry is also the value of the mutual inductance of two coils arranged such that an electromotive force of one volt is induced in one if the current in the other is changing at a rate of one ampere per second. See inductance.
