Fetola matšoao a mantlha a ts'ebetso

Lenane la ts'ebetso ea coil ea inductance ke boholo ba boholo ba inductance. Ho phaella moo, ka kakaretso, leqeba la terata le inductance coil kamehla le na le khanyetso e itseng, eo hangata e leng nyenyane haholo 'me e ka hlokomolohuoa. Leha ho le joalo, ha motlakase o phallang lipotolohong tse ling o le moholo haholo, khanyetso ena e nyenyane ea coil e ke ke ea hlokomolohuoa, hobane motlakase o moholo o tla ja matla holim'a coil, e leng se etsang hore coil e chese kapa e chese, kahoo ka linako tse ling motlakase. matla ao sekoele se ka mamellang se lokela ho nahanoa.

Inductance

Inductance l e emela litšobotsi tsa tlhaho tsa coil ka boeona, ho sa tsotellehe hore na ke ea hona joale. Ntle le coil e khethehileng ea inductance (color-coded inductance), inductance hangata ha e tšoauoa ka ho khetheha holim'a coil, empa e tšoauoa ka lebitso le itseng. Inductance, eo hape e tsejoang e le "self-inductance coefficient", ke palo ea 'mele e bontšang bokhoni ba ho inductance ba inductor. The inductance ea inductor haholo-holo e itšetlehile ka palo ea ho chenchana ha li-coil, mokhoa oa ho pota-pota, ho ba teng kapa ho ba sieo ha mantlha le thepa ea mantlha, joalo-joalo. kholo ea inductance. The inductance ea coil e nang le matla a khoheli e kholo ho feta ea coil ntle le motheo oa makenete; Ha matla a khoheli a phunyeletsa mokokotlong, ho na le matla a maholo ho feta.

Sehlopha sa mantlha sa inductance ke Henry (Hen ka bokhutšoanyane), e emeloang ke lengolo "H". Liyuniti tse sebelisoang hangata ke milli-Heng (mH) le micro-Heng (μH), 'me kamano lipakeng tsa tsona ke:

1H=1000mH

1mH=1000μH

Boitšoaro ba ho susumetsa

Boholo ba khanyetso ea khoele ea inductance ho AC hajoale e bitsoa inductance XL, ka ohm e le yuniti le ω joalo ka letšoao. Kamano ea eona le inductance L le AC frequency F ke XL=2πfL.

Ntlha ea boleng

Ntlha ea boleng Q ke bongata ba 'mele bo emelang boleng ba coil,' me Q ke karo-karolelano ea inductance XL ho khanyetso ea eona e lekanang, ke hore, Q = XL/R. inductor e sebetsa tlas'a motlakase o itseng oa AC. Ha boleng ba Q ba inductor bo phahame, tahlehelo e nyane le ts'ebetso e phahameng. Boleng ba q ba coil bo amana le khanyetso ea DC ea mokhanni, tahlehelo ea dielectric ea skeleton, tahlehelo e bakoang ke thebe kapa mokokotlo oa tšepe, tšusumetso ea phello e phahameng ea letlalo le lintlha tse ling. Theko ea q ea khoele hangata ke mashome ho isa ho makholo. Ntho ea boleng ba inductor e amana le khanyetso ea DC ea terata ea coil, tahlehelo ea dielectric ea foreimi ea coil le tahlehelo e bakoang ke motheo le thebe.
