WebAmmeters are connected in series with whatever device’s current is to be measured. A series connection is used because objects in series have the same current passing through them. (See Figure 21.28, where the ammeter is represented by the symbol A.) Figure 21.27 (a) To measure potential differences in this series circuit, the voltmeter (V ... 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.
