5 lut 2007 · 1. How do I convert watts to ohms? To convert watts to ohms, you will need to use the formula W = V²/R, where W is the power in watts, V is the voltage in volts, and R is the resistance in ohms. 2. Why do I need to convert watts to ohms? Converting watts to ohms allows you to calculate the resistance needed for a specific amount of power to be ...
Calculate the amount of power dissipated by this electric heating element, if the generator's output voltage is 110 volts and the heater's resistance is 2.5 ohms: ( P = V2/ R ) Now, calculate the power dissipated by the same heater if the generator's output voltage is doubled.
