Volts to Watts - Calculator, how to convert, examples, table formula
volts across the resistor at . 3. amps, and since . W = V x I, our resistor will convert . 21. watts of power into heat. That means our resistor must be rated for an *absolute minimum* of 21 watts. A larger wattage resistor will run cooler, and it's good practice to use a resistor rated for at least 50% higher wattage than You expect to handle.
