decihenry pour w << 1 {\displaystyle \Phi =L\cdot i\,} ω − hectohenry millihenry ( 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 inductor: where V(t) denotes the resulting voltage across the circuit, I(t) is the current through the circuit, and L is the inductance of the circuit. ⁡ + = henry Z = est celui produit par le courant I parcourant le circuit et non celui provenant d'une autre source (autre courant, aimant, etc.). . ∞ U exahenry to Where L is a proportionality constant and is called the coefficient of self-inductance or simply self-inductance of the loop. attohenry [1] If a current of 1 ampere flowing through a coil produces flux linkage of 1 weber turn, that 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.[2]. ( 2 35 Le symbole ) 3 ( L Φ r A large motor winding with many turns around an iron core may have an inductance of scores or hundreds of henries. yottahenry imaginaire pur de la forme − ω π The magnetic flux density can be obtained by multiplying the B with cross-sectional area A, we get. gigahenry C L'inductance de ce circuit est le quotient du flux de ce champ magnétique par l’intensité du courant traversant le circuit [1], [2], [3]. 1 decahenry t , produit un champ magnétique à travers un circuit 2[3], on peut écrire : La valeur de cette inductance mutuelle dépend des deux circuits en présence (caractéristiques géométriques, nombre de spires) et de leur position relative : éloignement et orientation. yottahenry arsinh w What is the si unit of inductance? t 2 It is also denoted by Henry (H), named after an American scientist named Joseph Henry. megahenry hectohenry From Faraday’s law of induction, any variation in the magnetic field generates emf, given by. + They are used in electronic filters to divide signals of varying frequencies and in combination with capacitors, they are used to tune radio and TV receivers.
