Formula for power dissipated
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. WebA circuit element dissipates or produces power according to P = I V, P = I V, where I is the current through the element and V is the voltage across it. Since the current and the voltage both depend on time in an ac circuit, the instantaneous power p(t) = i(t)v(t) p ( t) = i ( t) v ( t) is also time dependent.
