An ammeter measures the electric current in a circuit. The name is derived from the name for the SI unit for electric current, amperes (A). In order for an ammeter to measure a device’s current, it must be connected in series to that device. This is necessary because objects in series experience the same current.
Electric currents are measured in amperes (A), hence the name. For direct measurement, the ammeter is connected in series with the circuit in which the current is to be measured. An ammeter usually has low resistance so that it does not cause a significant voltage drop in the circuit being measured.
An ammeter measures the current through an electrical component. Here are a couple of examples you might find in a school lab: Left: A digital ammeter. Right: An analogue ammeter. This is the symbol for an ammeter, which we'll use on circuit diagrams: "measures Amps" → Amp-meter → Ammeter. So how do we use an ammeter?
Ammeters should be connected to an electrical circuit in series in order to properly measure the flow of current through the complete circuit. Connecting an ammeter is likely to cause a short circuit (an interruption in the current flow), resulting in damage. What is the Difference Between AC Ammeters and DC Ammeters?
They must not be connected to a voltage source — ammeters are designed to work under a minimal burden, (which refers to the voltage drop across the ammeter, typically a small fraction of a volt). Ammeter in Series: An ammeter (A) is placed in series to measure current. All of the current in this circuit flows through the meter.
They mean exactly the same thing! An ammeter is connected in series with a bulb. The ammeter reads 5A, therefore the current through the bulb is 5A. Why does an ammeter need to be in series? An ammeter doesn't actually measure the current through other components — it measures the current through itself!
