How is wattage measured in time
Web16 mrt. 2024 · Watts are calculated by multiplying the voltage by the current in a DC circuit. Power in watts is the rate at which energy is either consumed or generated. One watt equals one joule (a measure of energy) per second (1 W + 1 J/s). Utility companies charge rates based on watts, or power consumed over a given time. WebThe equation for time in this page’s context is given above right. Example: An LED light bulb is rated at 12 watts, and over a period of time is measured to have used 4,200 joules. How long was the light on for? In this case we simply enter the energy used (4,200 J) and power rating (12 W) into the calculator and click Calculate. The answer is 350 seconds exactly.
