What does the term "wattage" describe?

The term "wattage" specifically refers to the rate of energy consumption. It is a measure of how much electrical energy is converted into other forms of energy, such as heat and light, in a given amount of time. Wattage is quantified in watts, with one watt equating to one joule per second. This concept is fundamental in understanding how electrical devices utilize power; for example, a 60-watt light bulb consumes 60 joules of energy every second it is in use.

In the context of electrical circuits, wattage is crucial for determining how much power a device will use from an electrical supply, influencing everything from energy efficiency to electrical bill calculations. Understanding wattage helps users choose appropriate devices and maintain their electrical systems efficiently.
