There, he conducted experiments for creating a transformer. The name "transformer" was created by Bláthy. [citation needed] In 1885 the ZBD model alternating-current transformer was invented by three Hungarian engineers: Ottó Bláthy, Miksa Déri and Károly Zipernowsky. (ZBD comes from the initials of their names). In the autumn of 1889 he ...
In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits.A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core.
Ottó Bláthy also discovered the transformer formula, Vs/Vp = Ns/Np. [31] Electrical and electronic systems the world over rely on the principles of the original Ganz transformers. The inventors are also credited with the first use of the word "transformer" to describe a device for altering the EMF of an electric current. [30] [32]
Irish priest (and later scientist) Nicholas Callan invented the transformer in Ireland 1837: English scientist Edward Davy invented the electric relay: 1839: French scientist Edmond Becquerel discovered the Photovoltaic Effect: 1844: American inventor Samuel Morse developed telegraphy and the Morse code 1844
The "closed primary, open secondary" resonant transformer circuit used by Tesla proved a superior transmitter, [92] because the loosely-coupled transformer partially isolated the oscillating primary circuit from the energy-radiating antenna circuit, reducing the damping, allowing it to produce long "ringing" waves which had a narrower bandwidth.
In 1885, Stanley built the first practical alternating current transformer based on Lucien Gaulard and John Dixon Gibbs' prototype of 1881. This device was the precursor to the modern transformer . In December, under a new contract with Westinghouse, Stanley moved his operations to Great Barrington, Massachusetts .
In 1845, Faraday discovered that many materials exhibit a weak repulsion from a magnetic field: an effect he termed diamagnetism. [ 65 ] Faraday also discovered that the plane of polarization of linearly polarised light can be rotated by the application of an external magnetic field aligned with the direction in which the light is moving.
So, Callan tried making a bigger coil. With a battery of only 14 seven-inch (178 mm) plates, the device produced power enough for an electric shock "so strong that a person who took it felt the effects of it for several days". Callan thought of his creation as a kind of electromagnet; but what he actually made was a primitive induction transformer.
