1.	Heat sinks work through the process of _______(a) resistive heat transfer(b) conductive and convection heat transfer(c) active process(d) no heat transferI got this question in an interview.The question is from Transistor Case and Heat Sinks in portion Differential and Multistage Amplifiers of Electronic Devices & Circuits
Answer» Correct ANSWER is (b) CONDUCTIVE and convection heat transfer The explanation: The main purpose of a heat sink is to expel heat from a generating source. Heat sinks work through the process of conductive and convection heat transfer. Heat sinks are a passive form of COOLING, as they have no moving parts and REQUIRE no power. In most cases, heat sinks are USED in conjunction with fans.
