WebIt measures direct and alternating current (by using a rectifier to convert the AC to DC) with accuracies of 0.1 to 0.25 percent. In the thermal (or hot-wire) ammeter, used primarily to measure AC with accuracies of 0.5 to 3 percent, the measured current heats a piece of wire, and the current is indicated by how much the wire expands. WebAn ammeter is connected in series with the circuit to measure the entire flow of electrons (current). The measured current and the internal resistance of the ammeter are the sources of power loss in the device. The ammeter circuit offers low resistance so that a small voltage drop occurs in the circuit. Effect of Temperature On Ammeter
