Menene hFE akan multimeter
hFE yanki ne na ma'auni don tantance riba (ko riba) na yanzu wanda transistor zai iya bayarwa. A wasu kalmomi, hFE shine rabo tsakanin abubuwan shigarwa na halin yanzu da sakamakon fitarwa na yanzu, kuma ana iya amfani dashi don sanin yadda ya dace da wani transistor na musamman don kewayawa ko aikace-aikace.
hFE akan na'urar multimeter wani abu ne da ke auna karuwa ko raguwar ƙarfin wutar lantarki tsakanin maki biyu, wato "ƙimar hFE akan na'urar multimeter tana nuna yawan halin yanzu da transistor zai iya ɗauka kafin ya fara zafi kuma ya kasa." Misali: lokacin shigar da halin yanzu volt daya ne a maki A da kuma amp daya na shigar yanzu a maki B, karfin fitarwa zai zama sau daya amp sau daya volt sau hFE. Idan hFE shine 10, fitarwa na yanzu zai zama amps goma.
Bayanin hFE
Don karya wannan ma'auni, zamu iya ganin cewa Ic shine "mai tattarawa" kuma Ib shine "base current". Lokacin da aka raba waɗannan sharuɗɗan biyu tare, za mu sami riba na yanzu na transistor, wanda aka fi sani da hFE.
Menene ma'anar hfe?
hFE yana nufin "Hybrid Direct Emitter". Ana kuma san shi da "beta na gaba" a wasu lokuta. Kalmar ta zo daga gaskiyar cewa rabon da yake wakilta shine haɗuwa da ma'auni daban-daban guda biyu: musamman tushen juriya na yanzu da juriya na yanzu. An ninka su tare don ƙirƙirar abin da muka sani da hFE.
Menene gwajin hFE?
Gwajin yana auna riba (ko riba) na transistor. An bayyana riba azaman rabon siginar fitarwa zuwa siginar shigarwa. Hakanan ana kiranta da "beta" (β). Transistor yana aiki azaman amplifier, yana ƙara ƙarfin halin yanzu ko ƙarfin lantarki a abin da yake fitarwa dangane da shigarwar sa, yayin da yake riƙe da ƙarfin fitarwa akai-akai. Don sanin ko transistor zai yi aiki mai kyau a aikace, dole ne a gwada ribarsa kuma a kwatanta shi da abin da ake buƙata don wannan aikace-aikacen. (1)
Yaya ake lissafin hFE?
Ana ƙididdige hFE ta hanyar kwatanta tushen halin yanzu da na yanzu mai tarawa. Ana kwatanta waɗannan magudanar ruwa guda biyu ta hanyar amfani da gwajin gwaji wanda ke ba ka damar gwada transistor da ake tambaya. Na'urar gwaji ta transistor tana riƙe da tushen halin yanzu a matakin akai-akai sannan kuma yana auna halin yanzu mai tarawa da ke gudana ta cikinsa. Da zarar kun sami waɗannan ma'auni guda biyu, zaku iya ƙididdige hFE.
Duk da haka, akwai wasu ƴan mahimman bayanai ga wannan hanyar gwajin transistor ɗin ku. Misali, ya kamata ku sani cewa idan kun auna rukunin transistor tare, za su tsoma baki cikin karatun juna. Wannan yana nufin cewa idan kuna son auna daidai ƙimar hFE na transistor ku, yana da kyau a gwada su ɗaya bayan ɗaya. Duk da yake wannan na iya rage aikin gwajin, yana kuma tabbatar da daidaiton sakamakon.
