Microammeter EDM

Lub hom phiaj dav dav Microammeter, haum rau tsev kawm ntawv chav ntsuas ntsuas microcurrent thiab microvoltage hauv DC cicuit. Nws tuaj yeem ua kom rov qab tau qhov kev sim ntawm galvanometer, voltmeter, daim npav tsis kam, thiab hauv kev sim los ntsuas qhov muaj peev xwm tam sim no los ntawm kev siv cov ntsuas hluav taws xob thiab qhov siab tso tawm.– Nrog kev tiv thaiv Circuit Court ntawm silicon diode ntawm 'meter' ib pab tub rog, pub dawb los ntawm kev sib tshooj ntau dhauTshiab teev qhov tseeb ntawm?
