Árammérket

Árammérket is a term of Hungarian origin that translates to "current marker" or "amperemeter." In the context of electrical engineering and physics, it refers to a device used to measure electric current. These instruments are fundamental for understanding and controlling electrical circuits.

An árammérket typically displays the magnitude of the current flowing through it, usually in amperes (A) or milliamperes (mA). They operate on various principles, including the magnetic effect of electric current, the thermal effect, or the electrodynamic effect. Common types include analog árammérők, which use a needle to indicate the current on a calibrated scale, and digital árammérők, which display the current as a numerical value.

When using an árammérket, it is crucial to connect it in series with the circuit component through which the current is to be measured. This ensures that all the current passes through the instrument for accurate reading. Improper connection, such as connecting it in parallel, can lead to damage to the meter or the circuit itself due to excessive current. The sensitivity and range of an árammérket are important considerations when selecting the appropriate device for a given application.
