Coulombräknare

Coulombräknare is a term that appears in some contexts related to electrical measurements. While not a standard scientific unit or instrument, it likely refers to a device or method for quantifying electric charge, measured in coulombs. The name suggests a direct link to the coulomb, the SI unit of electric charge, named after the French physicist Charles-Augustin de Coulomb. Therefore, a coulombräknare would essentially be a charge meter or coulomb counter. Such devices are used to measure the total amount of electric charge that has passed through a circuit over a given period. This can be particularly useful in applications involving batteries, electrolysis, or electrostatic experiments where tracking charge accumulation or discharge is important. The specific implementation of a coulombräknare could vary, perhaps involving integration of current over time or direct measurement of charge carriers.
