In an analog ammeter, the internal shunt resistor is a small resistance. It is in parallel with the galvanometer, so the ammeter has very small resistance. In an analog voltmeter, the internal shunt resistor is a large resistance. It is in series with the galvanometer, so the voltmeter has very large resistance.

Work Step by Step

Compare Figure 19-31 (an analog ammeter) to Figure 19-32 (an analog voltmeter).
