Inductance feem ntau qhia raws li micro- Henries , uas sawv cev rau 1,000,000 Henries . Hloov ua lwm yam Henries , koj yuav faib tus naj npawb ntawm micro- Henries los ntawm 1, 000, 000. xam reactance, hauv ohms, los ntawm kev siv cov mis: Reactance = 2 * pi * Zaus * Inductance. Pi tsuas yog qhov tsis tu ncua, ntsuas li 3.14.

Tsis tas li ntawd, henries raug xam li cas?

xam inductance siv lej qauv . Siv cov qauv L = R * sqrt(3) / (2 * pi * f). L yog qhov inductance, yog li koj xav tau qhov tsis kam (R) thiab zaus (f) koj xav tau ua ntej.

Ib sab saum toj, koj ntsuas qhov impedance ntawm lub kauj li cas? Yog xam impedance , xam cov tsis kam thiab reactance ntawm Circuit Court, ces daim ntawv lo tsis kam raws li R thiab reactance li X. Square ob qho tib si R thiab X, thiab ntxiv ob qho khoom ua ke. Siv lub hauv paus square ntawm cov lej ntawm cov squares ntawm R thiab X kom tau impedance . Tso cov lus teb hauv ohms.

Cov mis rau reactance yog dab tsi?

Cov qauv rau xam qhov inductive reactance Ib co coil yog: inductive reactance , sau XL, yog cov khoom ntawm 2 zaug p (pi), lossis 6.28, zaus ntawm ac tam sim no, hauv hertz, thiab inductance ntawm lub kauj, hauv henries. XL =2p x f x L. L = tus nqi inductance ntawm lub kauj hauv henries.

Yuav ua li cas koj xam qhov cheeb tsam ntawm ib lub kauj?

cheeb tsam = cross sectional cheeb tsam ntawm cov tub ntxhais hauv square metres *, suav nrog qee qhov coil raws li qhia hauv daim duab. length = ntev coil hauv meters *
