What Is an Ammeter?
Among its many uses, electricity heats and lights our homes, makes our cars start up when we turn the key, and powers all our electronic devices. Sometimes we need to measure the electricity flowing through these devices. One of the instruments that can do this is the ammeter, which measures electric current. It gets its name from the standard unit of measurement for electric current, the ampere. Often you will see the word ampere shortened to amp. Nowadays, the job of an ammeter is often done with another, more versatile instrument called a multimeter, which can measure more than just current.
Current vs. Voltage
It is important to note that an ammeter only measures current, not voltage. Current and voltage are two separate quantities. Voltage can be defined as the electric potential difference per unit charge. It can be viewed as the energy contained within an electric circuit or field at a single point. Current, on the other hand, is the rate at which electric charge passes any given point on a circuit.
One common way to try and understand the difference between the two is to view electricity moving through a wire like water moving through a hose. In this analogy, voltage is like water pressure, and current is like the water flow rate. Changes to one can affect the other, but they are not the same thing.
Ammeters tend to influence the amount of current in the circuits they're connected to. However, unlike the ideal voltmeter, the ideal ammeter has zero internal resistance, so as to drop as little voltage as possible as current flows through it.
