Web7 de abr. de 2024 · Determine resistor wattage. If you want to know wattage of a resistor, you will need to know the voltage (V) and the current (known as I). This is called Ohm’s law. The multiplication formula is voltage multiplied by current, expressed as W=V X I. .Sometimes you will see the formula written with a P for power. Web31 de out. de 2000 · The power output of the light bulb is 100 watts. Using the equation I = P/V, we can calculate how much current in amps would be required to get 100 watts out of this 6-volt bulb. You know that P = 100 W, and V = 6 V. So, you can rearrange the equation to solve for I and substitute in the numbers. I = 100 W/6 V = 16.67 amps. chinese work ethic culture
