Henry (unit) Henry (unit) The henry (symbol: H) is the SI derived unit of electrical inductance. If a current of 1 ampere flowing through the coil produces flux linkage of 1 weber turn, the coil has a self inductance of 1 henry.‌ The unit is named after Joseph Henry (1797–1878), the American scientist who discovered electromagnetic induction independently of and at about the same time as Michael Faraday (1791–1867) in England. The inductance of an electric circuit is one henry when an electric current that is changing at one ampere per second results in an electromotive force of one volt across the
The Civil Wars: A Tree Is Best Measured When It Is Down and a principal writer was Lebanese poet Etel Adnan, though the collage-like libretto incorporated a diverse collection of texts. Bryars set a speech by Marie Curie, "I am among those who believe that science has a great beauty", a poem by Pope Leo XIII on the then-new art of photography, and a speech by an imaginary scientist in Jules Verne's "20,000 Leagues Under the Sea". The work was not completed or publicly performed, but Bryars incorporated a number of its arias into the later works "Effarene" and "On Photography". The Civil Wars: A Tree Is Best Measured When It Is
