WebWe can use Ohm’s Law which states that V = I*R, and replace the voltage for temperature (T) and current for power (P), which gives us: The equivalent thermal circuit is shown below where: T_Junction (TJ): the junction temperature RθJC: the junction to case thermal resistance T_Case (TC): the junction temperature topic argumentsWeb8. Power is P = I V. You can only relate it to resistance if you decided to fix one and replace the other by Ohm's law. Ohm's law states that voltage across a resistor is linearly proportional to the current flowing through it, or V = I R. This can be arranged to say that current is inversely proportional to voltage, or I = V R. topic computing
