Download Diagram Of Ammeter PNG. As we know, the unit of current is ampere. The ammeter is a measuring instrument used to find the strength of current flowing around an electrical circuit when connected in series with the part of the circuit being measured.
Symbol For Ammeter - ClipArt Best from www.clipartbest.com This work presents a contactless ammeter prototype based on gmr magnetometers, able to measure direct and alternating electrical currents. Ammeters must be connected in series with the current to be measured, to ensure that all the current moves through the meter If the current instead is flowing from lower potential to higher potential, then the current is a negative value.

Explain why ammeters use fuses and voltmeters do not? Voltmeters measure voltage, whereas ammeters measure current. Most ammeter fuses can be easily replaced or reset, though this process will vary according to your brand and model. Schematic diagram of digital ammeter with complete separated power supply:
