WebWe can calculate the power released in the bulb, and of the electrical system as a whole, by multiplying the voltage by the current. So, to calculate watts, the following formula is used. How to Calculate Watts W = V * I For example, a current of 2A flowing through a bulb with a voltage of 12V across it generates 24W of power. WebOct 4, 2024 · But watts don’t actually measure brightness at all. What Do Watts Measure? You might remember learning the equation to determine watts in your physics class: W=(A)(V). Watts are increments of power, the result of amps being under the pressure of volts. So a light bulb with a higher wattage will use more power than one with a lower …
