1.How do digital ammeters and voltmeters work?

• A shunt resistor is used in digital ammeter designs to produce a calibrated voltage proportional to the current flowing. This voltage is then measured by a digital voltmeter using an analog-to-digital converter (ADC); the digital display is calibrated to display the current flowing through the shunt.

2.What is the working Principle of ammeter?

• The magnetic effect of current drives the ammeter's principle, which states that resistance and inductive reactance must be low. An ammeter is made up of a wire coil and a fixed permanent magnet. As a result, an ammeter cannot be connected in a parallel line.

3.Is ammeter DC or AC?

• The ammeter, a device used to measure direct (DC) or alternating (AC) electric current in amperes. An ammeter can measure a wide range of current values because at high values only a small portion of the current is directed through the metre mechanism; the majority is carried by a shunt connected in parallel with the metre.
