Henry (H) Eenheid definisie

The inductance of an electric circuit is one henry when an electric current that is changing at one ampere (A) per second (s) results in an electromotive force of one volt (V) across the inductor: V(t) = L ^dI⁄_dt, 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.

The henry is a derived unit based on four of the seven base units of the International System of Units: kilogram (kg), meter (m), second (s), and ampere (A). Expressed in combinations of SI units, the henry is: H = ^kg∙m2⁄_s²∙A² = ^N∙m⁄_A² = ^kg∙m2⁄_C² = ^J⁄_A² = ^T∙m2⁄_A = ^Wb⁄_A = ^V∙s⁄_A = ^s2⁄_F = ^Ω⁄_Hz = Ω∙s. Where: H = henry, kg = kilogram, m = meter, s = second, A = ampere, N = newton, C = coulomb, J = joule, T = tesla, Wb = weber, V = volt, F = farad, Ω = ohm, Hz = hertz.

Die Internasionale Stelsel van eenhede (SI) spesifiseer om die simbool te skryf van 'n eenheid wat vernoem is vir 'n persoon met 'n aanvanklike kapitaalbrief, terwyl die naam nie in sinteks gekapitaliseer word nie, behalwe as enige woord in daardie posisie gekapitaliseer sou word, soos by die begin van 'n sin of in materiaal met behulp van titelsaak. Die Amerikaanse Nasionale Instituut vir Standaarde en Tegnologie beveel gebruikers aan om in Engels te skryf om die meervoud as Henries te gebruik.

The inductance of a coil depends on its size, the number of turns, and the permeability of the material within and surrounding the coil. Formulas can be used to calculate the inductance of many common arrangements of conductors, such as parallel wires, or a solenoid. A small air-core coil used for broadcast AM radio tuning might have an inductance of a few tens of microhenries (μH). A large motor winding with many turns around an iron core may have an inductance of hundreds of henries. The physical size of an inductance is also related to its current carrying and voltage withstand ratings.
