[QUOTE="struggling:(, post: 2737554, member: 209609"] [h2]Homework Statement [/h2] An LED is connected as shown (see attached) When switch S is closed: A. the p-n junction is reverse biased and free charge carriers are produced which may recombine to give quanta of radiation. B. the p-n junction is forward biased and positive and negative charge carriers are produced by the action of light. C. the p-n junction is reverse biased and positive and negative charge carriers are produced by the action of light. D. the p-n junction is forward biased and positive and negative charge carriers may recombine to give quanta of radiation E. the p-n junction is reverse biased and positive and negative charge carriers may recombine to give quanta of radiation. [h2]Homework Equations[/h2] - [h2]The Attempt at a Solution[/h2] Question came up on the multiple choice section in an exam, took a guess at E but was looking for a hint? Thanks in advance, [/QUOTE]
