Why there is a need for heat sinks in Class A amplifier?(a) To control the external temperature(b) To avoid temperature changes affecting the transistor(c) To control heat dissipation(d) To increase output resistanceThis question was posed to me during an interview.This question is from Class A Large Signal Amplifiers in division Large Signal Amplifiers of Electronic Devices & Circuits |

Answer» RIGHT CHOICE is (c) To CONTROL heat dissipation To explain: When even no input is GIVEN to class A amplifiers, it produces some current to load, and hence heat sinks are required to avoid this. |
