WebDec 4, 2024 · If the circuit you're measuring has a relatively low impedance (less than maybe 20x the shunt resistance) as measured from the points you connected the ammeter, then the choice of range will affect the measured current. WebA device called a DC ammeter is used to measure the amount of DC current flowing through a circuit. The scale on the DC ammeter represents current in amperes. A basic movement can only carry exceedingly small currents because the coil winding is light and small. WebDC Ammeter – The PMMC galvanometer constitutes the basic movement of a dc ammeter. Since the coil winding of a basic movement is small and light, it can carry only very small currents. When large currents are to be measured, it is necessary to bypass a major part of the current through a resistance called a shunt, as shown in Fig. 3.1. bishop mccort class of 1971 reunion
