Amathegi womkhiqizo

Uhlobo lwesikhombi i-ammeter ne-voltmeter ekhishwa ekhanda lemitha. Inhloko yemitha ivamise ukuba yi-magnetoelectric galvanometer, evumela kuphela ukuthi manje izinga le-micro ampere noma le-milliampere lidlule. Ngokuvamile, ingalinganisa kuphela manje amandla nogesi omncane kakhulu. Ekusebenziseni okusebenzayo, kufanele iguqulwe ukuze ikhulise ububanzi bayo bokulinganisa uma izolinganisa i-current enkulu noma i-voltage. Imitha eguquliwe kufanele ilinganiswe ngemitha ejwayelekile futhi kufanele kunqunywe izinga layo lokunemba. Leli thuluzi linikeza isethi ephelele yemishini yokuhlola yokufaka i-ammeter encane ku-milliammeter noma i-voltmeter. Okuqukethwe kokuhlola kucebile, umqondo ucacile, uzinzile futhi unokwethenjelwa, futhi ukwakheka kwesakhiwo kunengqondo. Ingasetshenziselwa ikakhulukazi isivivinyo sokunwetshwa kwe-physics sabafundi besikole samabanga aphakathi noma isivivinyo sekholeji ejwayelekile se-physics kanye nesilingo sokuqamba.

Imisebenzi

1. Qonda ukwakheka okuyisisekelo nokusetshenziswa kwe-microamp galvanometer;

2. Funda ukuthi unganweba kanjani ububanzi besilinganiso se-galvanometer futhi uqonde umgomo wokwakha i-multimeter;

3. Funda indlela yokulinganisa imitha kagesi.
