Watt-hour
A Watt-hour (Wh) is a unit of energy that measures the amount of electrical energy consumed or generated over time. One Watt-hour is equivalent to one watt of power used or produced for one hour. This unit is commonly used to quantify energy usage in households, industries, and various devices. For instance, a 100-watt light bulb running for 10 hours consumes 1000 watt-hours, or 1 kilowatt-hour (kWh). Watt-hours are essential for understanding energy consumption, billing in electric utilities, and managing energy efficiency.
Kilowatt-hour
A Kilowatt-hour (kWh) is a unit of energy that measures the amount of electrical energy consumed or generated over time. One kilowatt-hour is equivalent to one kilowatt (1,000 watts) of power used or produced for one hour. This unit is commonly used to quantify energy usage in households, industries, and various devices. For example, if a 1,000-watt appliance runs for one hour, it consumes 1 kWh of energy. Kilowatt-hours are essential for understanding energy consumption, billing in electric utilities, and managing energy efficiency.
