WebQ3 A generator has a 500 MW output power and a 95% efficiency. The generator is located in ambient air temperature of 33°C. Rth = 6x10-6 K/W Cth = 70x10+6 J/K a. Calculate … WebThen with an accurate measurement of temperature at that point (Tx) the true thermal resistance can be calculated as: Rth (JX_Ө) = (Tj –Tx) / P. Where P is the dissipated power (heat) that flows from the junction to the point ‘X’. Ideally, during this measurement, close to 100% of the power should flow from the junction to the point ‘X’.
