elektrienergiaühiku

Elektrienergiaühiku, also known as the kilowatt-hour (kWh), is the standard unit for measuring electrical energy consumption. It represents the amount of energy consumed by a device using one kilowatt of power for one hour. Essentially, it quantifies how much electricity has been used over a period of time. For instance, if a 100-watt light bulb (which is 0.1 kilowatts) is left on for 10 hours, it will consume 1 kilowatt-hour of electricity (0.1 kW * 10 h = 1 kWh). This unit is widely used by utility companies to bill customers for their electricity usage, as it provides a consistent and easily understandable measure of energy consumed. The price of electricity is typically quoted per kWh. Understanding the elektrienergiaühiku is crucial for managing household energy consumption and identifying areas where energy efficiency can be improved.
