1.	When the power dissipation increases in a transistor, the thermal resistance_________(a) increases(b) cannot be predicted(c) decreases(d) remains sameI got this question in a national level competition.My enquiry is from Thermal Runaway topic in portion Transistor Biasing and Thermal Stabilization of Electronic Devices & Circuits
Answer» Correct option is (c) decreases The BEST explanation: The power dissipation is directly PROPORTIONAL to thermal RESISTANCE. We have, TJ – TA = θPd in which we can observe θ ∝ 1/Pd. So, a device with LOW power dissipation has high thermal resistance.
