How is electric power related to resistance
WebElectric power is the ... R is the resistance and P is the electric power. Hope you have understood Electric energy and power, How it is defined, its Symbol, Units, Formula, and Terms. For a better understanding of … WebTo better understand how thermal resistance is used, lets look at the following example: Power dissipated: 2W. RθJC = 4°C/W. RθCH = 0.25°C/W. RθHA = 6°C/W. TA = 25°C. Starting with the thermal equivalent of Ohm's Law: We want to solve for our junction temperature rise , so T becomes T J. Our power dissipated, P, is 2W.
