Ammeter

OverviewApplicationHistoryTypesPicoammeterSee alsoExternal links

Ammeters must be connected in series with the circuit to be measured. For relatively small currents (up to a few amperes), an ammeter may pass the whole of the circuit current. For larger direct currents, a shunt resistor carries most of the circuit current and a small, accurately-known fraction of the current passes through the meter movement. For alternating current circuits, a current transformer

10.4 Electrical Measuring Instruments

Figure 10.35 (a) When an ammeter is used to measure the current through two resistors connected in series to a battery, a single ammeter is placed in series with the two resistors because the current is the same through the two resistors in series. (b) When two resistors are connected in parallel with a battery, three meters, or three separate ammeter …

Clamp ammeters are indispensable tools for modern electronic testing ...

Why do ammeters need to have zero resistance? : r/AskPhysics

An ideal measurement device should not affect the results of your measurement. If an ammeter has resistance than the current that flows through the circuit when the ammeter is present is not the same as the current that flows through the circuit when it is not.

Best Clamp Meters in 2024

Clamp meters have almost all basic functions like multimeters. Best clamp meters may have a current testing capacity up to 1000 amps, also 2500 amps with iflex extension.
