I need to work out the total resistance of a heating element made up of 3 strips of resistive material in paralell. We are told that the unit is 12V and theheat is generated at a rate of 40W, I need to calculate the total resistance of the element. I kno I have to use the formular R=v²/r where R is the resistance, V is the voltage and r is the power(watts). i know that the voltage will be the same across all the strips but will the power, could you help me please?(adsbygoogle = window.adsbygoogle || []).push({});
