1.	Which of the following is not an advantage of using a LED?(a) High response time(b) Compatibility with solid-state circuits(c) Rugged construction and high lifetime(d) No need for a heat sink in long runI had been asked this question during a job interview.This question is from Types of Diode and their Testing in section Diode Circuit of Analog Circuits
Answer» The correct ANSWER is (d) No need for a heat sink in LONG RUN To explain: The response time of a LED is typically in the order of nanoseconds. The operating voltage range for LED is between 1.7 V to 3.3 V which makes it compatible with solid-state circuits. Also, the semiconductor construction makes them RUGGED. However, in the long run, an adequate heat sink is required for longevity.
