Ammeter. The ammeter should read close to zero when the battery is completely charged and there is little electrical demand, but it should always be on the plus side of zero. After starting, it''s typical for the ammeter to read a high positive amperage in order to recharge the battery. Nevertheless, this positive amperage should soon begin to decline.

The tangent galvanometer was used to measure …
Project Overview. In this project, you will learn how to use a voltmeter to measure voltage. Typically, the voltmeter is one of the functions of a multimeter, which is an electrical instrument capable of measuring voltage, current, and resistance (Figure 1).. Figure 1. Digital and analog multimeters with test probes connected to measure voltage.
Let''s now introduce the voltmeter and the ammeter. A voltmeter is designed to measure the voltage across a portion of a circuit, while an ammeter is designed to measure the current passing through a particular point in the circuit. That is, the voltmeter stays outside the circuit, while the ammeter must be inserted into the circuit.

For a 6 V battery and a small lamp, the circuit current will be in the range of thousandths of an amp or milliamps (mA). Digital meters often show a small letter "m" on the right-hand side of the display to indicate this metric prefix.
Being able to accurately measure amperage of the current is crucial in determining whether the current is normal. Using a tool called ''ammeter'' or ''clamp meter'' to measure current makes it easy and accurate, and it is easy …
Since the shunt resistance is small, most of the current passes through it, allowing an ammeter to measure currents much greater than those producing a full-scale deflection of the galvanometer. Suppose, for example, an ammeter is needed that gives a full-scale deflection for 1.0 A, and contains the same 25-Ω galvanometer with its 50-μA ...
When the ammeter indicates a normal reading (not "backwards"), electrons are entering the black test lead and exiting the red. This is how you determine direction of current using a meter.
