Watts

Watts measure the rate at which energy is used or produced. Think of it as a way to quantify how quickly electricity, for example, powers a device. For instance, a 100-watt light bulb consumes energy at a rate of 100 joules per second. Higher wattage means more energy is used per time, resulting in a brighter lamp or more powerful motor. Watts help compare how much energy different appliances need or produce, making it easier to understand and manage energy consumption and efficiency.
