How well do you know about photodiodes? Here, we have a quiz based on that. The aim of this photodiode quiz is to provide you with accurate knowledge of the concepts of special diodes. A photodiode is a light-sensitive semiconductor device that follows a P-N junction rule. It converts photons into electrical currents. What else do you know about it? Have you ever worked or used such diodes? Just take the quiz below and improve your understanding of photodiodes.
