An analog ammeter makes use of a needle similar to that found in a compass needle. The needle points to the particular amount of current that passes through the ammeter. A digital ammeter displays the measured current on a liquid crystal display. Step 2 - Safety Preparations. Working with an ammeter means working with electrical current.
Consult your owner’s manual on the particular model of meter you own for details on measuring current. When an ammeter is placed in series with a circuit, it ideally drops no voltage as current goes through it. In other words, it acts very much like a piece of wire, with very little resistance from one test probe to the other.
Connect the ammeter leads to the circuit. This process will depend on your model of ammeter. Essentially, the negative ( - ) end of your ammeter will connect to the power source side of the broken circuit. The positive end (+) will connect to the opposite side, so that the ammeter bridges the break.
• Insert a spare piece of wire into the hole you just pulled the other wire or terminal out of. Leave the other end of this wire hanging in mid-air. • Connect the ammeter between the two unconnected wire ends (the two that were hanging in mid-air). You are now assured of measuring current through the wire or terminal initially identified.
The schematic diagram for measuring the current of the lamp circuit using an ammeter. Step 3: Verify that the lamp lights up before connecting the ammeter in series with it. Step 4: Break the circuit open, as illustrated in Figures 1 and 3, and connect the ammeter’s test probes to the two points of the break to measure current.
Using an ammeter to measure the current from a single battery. Step 5: Measuring the total current involves a similar procedure by breaking the circuit and inserting the ammeter, as shown in Figure 6.
The positive end (+) will connect to the opposite side, so that the ammeter bridges the break. Most ammeters use color coding to indicate positive and negative ends of a circuit. This may be different from country to country, but in many cases, red will represent positive and black negative.
