Elektriühik

An elektriühik is a unit of electric charge, energy, or power. In Estonia, the term can refer to different specific units depending on the context. When discussing electric charge, the standard SI unit is the coulomb. One coulomb is the amount of electric charge transported by a constant current of one ampere in one second. For electric energy, the joule is the standard SI unit, equivalent to one watt-second. However, in the context of electricity consumption and billing, the kilowatt-hour (kWh) is commonly used. One kilowatt-hour represents the energy consumed by a device with a power of one kilowatt operating for one hour. For electric power, the SI unit is the watt, defined as one joule per second. Understanding the appropriate elektriühik is crucial for accurate measurement and calculation in electrical engineering, physics, and everyday applications. The specific meaning of elektriühik will be clarified by its context within a sentence or a broader discussion about electrical phenomena or measurements.
