Kilowattórában

Kilowattórában is a unit of energy, commonly used to measure electricity consumption. The term is derived from the prefix "kilo" meaning one thousand, the unit "watt" which is a measure of power, and "hour" representing time. Therefore, a kilowatt-hour signifies the amount of energy consumed by a device with a power rating of one kilowatt operating for one hour.

In practical terms, if an appliance uses 1000 watts (1 kilowatt) of power, it will consume one kilowatt-hour of energy after running for one hour. Alternatively, a 100-watt appliance would need to run for 10 hours to consume the same amount of energy. This unit is widely adopted by utility companies to bill customers for their electricity usage, as it directly correlates to the amount of electrical energy that has been supplied and consumed. Understanding kilowatt-hours helps consumers monitor and manage their energy consumption to potentially reduce electricity costs.
