Qhov ntau ntawm milliammeter yog 0-500 mA. Muaj 20 qhov sib faib ntawm 0 thiab 100 mA ntawm nws qhov ntsuas.

Ib sab ntawm qhov no, uas muaj qhov siab dua ammeter lossis Milliammeter?

Txij li thaum, milliammeter yog rhiab dua, lub tsis kam yog qis hauv milliammeter . Rau qhov tsis tu ncua voltage, tam sim no los ntawm a milliammeter yuav tsum qis dua (hauv qhov kev txiav txim ntawm milliamperes) tab sis tam sim no los ntawm a ammeter yuav yog siab dua (nyob rau hauv qhov kev txiav txim ntawm amperes) yog li lub tsis kam hauv milliammeter yuav yog siab dua.

Tom qab ntawd, lo lus nug yog, yuav ua li cas koj hloov ntawm ammeter rau Milliammeter? Ib ammeter thiab a milliammeter yog hloov dua siab tshiab los ntawm tib galvanometer. Ntawm ob, qhov ntsuas twg muaj zog dua? Milliammeter tuaj yeem ua tau yooj yim los ntawm kev muab cov kab sib txuas nrog galvanometer, tom qab ntawd calibration yuav tsum tau ua. Yog li, tsis muaj shunt yuav tsum tau bypass tam sim no.

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog Milliammeter?

Kev kho mob txhais ntawm milliammeter : ib qho ntsuas ntsuas hluav taws xob hauv milliamperes - piv ammeter.

Yuav ua li cas koj hloov qhov ntau ntawm lub voltmeter?

Cov ntau yam ntawm voltmeter tuaj yeem nce ntxiv los ntawm kev sib txuas ntawm qhov tsim nyog siab resistors hauv koob nrog nws. 2. Cov ntau ntawm a voltmeter ntsuas tuaj yeem txo los ntawm kev txo nws cov resistace. Qhov no tuaj yeem ua tiav los ntawm kev muab qhov tsim nyog tiv thaiv nyob rau hauv parallel nrog cov voltmeter ntsuas.
