Kaliyar da Voltmetar, Ammetar da Wattmetar ta hanyar Potentiometar

Kalibrashin shi aikacewar gaskiya ta abubuwan da aka samun daga wani abu kafin haɗa da ma'anafi masu takaice. A cikin yadda aka baka, yana nuna gaskiyar zabin da ke amfani da ita ta hanyar haɗa da ma'anafi masu takaice. Wannan yanayi na iya sanya muna a matsayin bayanai da aka samu da kuma yi ayyuka don samun magana mai kyau.

Kalibrashin Voltmeter
Tarihin kalibrashin voltmeter ya ba a cikin hoton da ake bi.

Tarihi ya buƙata aiki da duhuwa rheostat: babu wanda ke amfani da ita don kawo shiga tsari, har zuwa wanda ke amfani da ita don kawo shiga mai zurfi. An amfani da voltage ratio box don kawo shiga tsarin tsari zuwa adadin da za a iya samun daidai. Gaskiyar voltmeter ya ba a cikin yadda ake samun tsari a cikin iyakkin potentiometer.

Potentiometer yana iya samun adadin da suka fi shi a tsari. Idan amsa potentiometer da voltmeter ba sa shi, za a samu abu mai karamin mutane ko karamin musamman a matsayin bayanai voltmeter.

Kalibrashin Ammeter

Tarihin kalibrashin ammeter ya ba a cikin hoton da ake bi.

An amfani da standard resistance a cikin series da ammeter da ke kalibrashin. Potentiometer an amfani da ita don samun tsari a cikin standard resistor. Tsarin da ke shiga a cikin standard resistance an tabbatar da ita da wannan formula:

ida:Vs shi ne tsari a cikin standard resistor, da ake samu daga potentiometer.S shi ne ma'anafi resistance na standard.Resistance na standard da tsari da ake samu daga potentiometer suna iya samun daidai saboda ake amfani da alama.Kalibrashin WattmeterTarihin da ake amfani don kalibrashin wattmeter ya ba a cikin hoton da ake bi.

An amfani da standard resistance a cikin series da wattmeter da ke kalibrashin. Low-voltage power source an amfani da ita don kawo shiga current coil na wattmeter. Rheostat an amfani da ita a cikin series da coil don kawo shiga adadin current.

Circuit na potential an kawo shiga electric supply. Voltage-ratio box an amfani da ita don kawo shiga tsarin tsari zuwa adadin da ake iya samun daidai da potentiometer. Adadin daidai na voltage da current an samu daga double-pole double-throw switch. Sannan, an haɗa VI (voltage-current) da amsa wattmeter.
