Iimpawu zemveliso

Uhlobo lwesikhombisi i-ammeter ye-DC kunye ne-voltmeter zikhutshiwe kwintloko yemitha. Intloko yemitha ihlala i-magnetoelectric galvanometer, evumela kuphela inqanaba le-micro ampere okanye le-milliampere ukuba lidlule. Ngokubanzi, inokulinganisa kuphela amancinci amancinci kunye nevolthi. Ukusetyenziswa okusebenzayo, kufuneka iguqulwe ukuze ikhulise uluhlu lwayo lokulinganisa ukuba ingakanani umda okhoyo ngoku okanye ombane. Imitha eguqulweyo kufuneka ilinganiswe ngemitha esemgangathweni kwaye inqanaba lokuchaneka kwayo kufuneka kumiselwe. Esi sixhobo sinika iseti epheleleyo yezixhobo zovavanyo lokumisa i-ammeter encinci kwi-milliammeter okanye kwi-voltmeter. Umxholo wolingo ucebile, umxholo ucacile, uzinzile kwaye unokwethenjelwa, kwaye uyilo lwesakhiwo lusengqiqweni. Ingasetyenziselwa ikakhulu ulingo lokwandiswa kwabafundi be-physics okanye ikholeji yokuvavanywa kwefizikiki ngokubanzi kunye novavanyo lokuyila.

Imisebenzi

1.Ukuqonda ubume obusisiseko kunye nokusetyenziswa kwe-microamp galvanometer;

2. Funda indlela yokwandisa uluhlu lwemilinganiselo yegalvanometer kwaye uqonde umgaqo wokwakha imultimeter;

3. Funda indlela yokulinganisa imitha yombane.
