Why is the ninth month called September?
masc. proper name, from French Henri, from Late Latin Henricus, from German Heinrich, from Old High German Heimerich, literally "the ruler of the house," from heim "home" + rihhi "ruler." One of the most popular Norman names after the Conquest.
henry hen·ry (hěn'rē)
n. pl. hen·rys or hen·ries (-rēz)
The unit of inductance in which an induced electromotive force of one volt is produced when the current is varied at the rate of one ampere per second.
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.
|Henry, Joseph 1797-1878. |
American physicist who studied electromagnetic phenomena. He discovered electrical induction independently of Michael Faraday, and constructed a small electromagnetic motor in 1829. He also developed a system of weather forecasting based on meteorological observations. The henry unit of inductance is named for him.
A king of England in the early sixteenth century. With the support of his Parliament, Henry established himself as head of the Christian Church in England, in place of the pope, after the pope refused to allow his marriage to Catherine of Aragon to be dissolved. Since that time, except for a few years of rule under Henry's daughter Mary I, who was a Roman Catholic, England has been officially a Protestant nation.
In his personal life, Henry was known for his corpulence and for his six wives. He divorced the first, Catherine of Aragon. He beheaded the second, Anne Boleyn, for allegedly being unfaithful to him. His third wife, Jane Seymour, died soon after giving birth to a son. He divorced his fourth wife, Anne of Cleves, and beheaded his fifth wife, Catherine Howard, also for alleged infidelity. His sixth wife, Catherine Parr, survived him. He also had his close friend and adviser Thomas More executed because More would not support Henry's declaration that he was head of the church in England. Henry was the father of King Edward VI and of Queen Elizabeth I, as well as Mary I.
(H) The SI unit of inductance: one henry is the inductance of a closed loop in which the induced voltage is one volt if the current flowing through it changes by one ampere each second, i.e., 1 H = 1 Vs/A. Named after the American physicist Joseph Henry (1797-1878).
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.
