A millihenry ( mH ) yog ib feem kaum ntawm SI muab tau los ntawm inductance henry. Henry txhais tau tias yog inductance ntawm ib lub voj voog, nyob rau hauv qhov kev hloov ntawm tam sim no nrog tus nqi ntawm ib ampere ib ob tsim electromotive quab yuam ntawm ib volt.

Cia li saib qhov no, koj yuav suav Millihenry li cas?

xam inductance siv lej qauv . Pib los ntawm kev sib npaug ntawm qhov tsis kam ntawm qhov resistor los ntawm lub hauv paus square ntawm 3. Piv txwv li, 100 ohms x 1.73 = 173. Tom ntej no, muab 2, pi, thiab zaus. Piv txwv li, yog tias qhov tsis kam yog 20 kHz: 2 * 3.14 * 20 = 125.6.

Qhov thib ob, SI unit ntawm inductance yog dab tsi? Lub henry (cim: H) yog tus SI muab tau chav tsev ntawm hluav taws xob inductance . Cov chav tsev muaj npe tom qab Joseph Henry (1797–1878), tus kws tshawb fawb Asmeskas uas tshawb pom electromagnetic induction nws tus kheej ntawm thiab tib lub sijhawm li Michael Faraday (1791–1867) hauv tebchaws Askiv.

Cov neeg tseem nug, koj yuav hloov Henry rau ohms li cas?

Chav tsev ntawm inductance yog 1H - henry . Yog li, kom tau Ohms faib los ntawm ib tug thib ob. Qhov ntawd tsuas yog tom qab koj faib qhov siv hluav taws xob los ntawm qhov ntsuas inductor tam sim no rau lub sijhawm ntawm ib thib ob.

Dab tsi yog inductance formula?

Yog li, magnetic inductance qauv txhais raws li qhov kev faib ua feem ntawm cov sib nqus flux nyob rau hauv lub caij ntxiv rau cov hluav taws xob tam sim no uas circulates los ntawm lub caij. Yog li ntawd, lub kev sib npaug yuav yog: L = ΦN/I. Ntawm no: L yog hais txog tus inductance.
