Dab tsi yog qhov tsis kam ntawm tus cwj mem hluav taws xob feem ntau?
1.5 megohms yog qhov qub. Qhov kev tawm tsam hauv tus cwj mem xeem feem ntau yog nyob ib puag ncig ob peb megohms.
Thaum tus cwj mem kuaj pom seb tus neeg xyuas pib puas yog cov xaim nyob lossis cov xaim nruab nrab, qhov tam sim no los ntawm kev ntsuas tus cwj mem (uas yog, tam sim no los ntawm tib neeg lub cev) Kuv=tag nrho qhov hluav taws xob U siv thoob plaws lub ntsuas ntsuas thiab tib neeg lub cev, muab faib los ntawm (/ yog sib npaug rau cov kab zauv feem) Ntsuas tag nrho cov tsis kam R hla tus cwj mem thiab tib neeg lub cev. Qhov kev tawm tsam hauv tus cwj mem xeem feem ntau yog nyob ib puag ncig ob peb megohms.
High voltage xeem cwj mem: siv rau 10kv thiab saum toj no tej yaam num, nws yog ib tug niaj hnub xeem cov cuab yeej rau electricians;
Tsawg voltage xeem cwj mem: siv rau them lub cev nrhiav kom tau kab voltage 500V thiab hauv qab no.
Tsis muaj zog tam sim no tus cwj mem: siv rau kev sim cov khoom siv hluav taws xob, qhov ntsuas qhov ntsuas dav dav yog 6v--24v. Rau kev yooj yim ntawm kev siv, feem ntau muaj cov hlau lead nrog ib qho clip ntawm qhov kawg ntawm tus cwj mem.
