WebVoltmeters can be used to measure the voltage drop across a single component or supply, or they can be used to measure the sum of voltage drops across two or more points or components within a circuit. For example, if we connect a voltmeter across the terminals of a fully-charged automobile battery, it will indicate 12.6 volts. WebTypically, the ammeter is one of the functions of a multimeter, which is an electrical instrument capable of measuring voltage, current, and resistance (Figure 1). Figure 1. Ammeter test probe connections for measuring current. Parts and Materials 6 V battery 6 V incandescent lamp
