What is the main difference between an analog v v., 8af63pwal)gugx goltmetey( 1mwzbs/35 7jvqzwz r and an analog ammeter?
参考答案:
An analog voltmeter has a
high value resistor in series with the galvanometer, so that the actual voltage
drop across the galvanometer is small.
An analog ammeter has a very low value resistor in parallel with the
galvanometer, so that the actual current through the galvanometer is
small. Another significant difference is
how they are connected to a circuit. A
voltmeter goes in parallel with the component being measured, while an ammeter
goes in series with the component being measured.
