To determine the reason why an LED produces light only when the n- and p-type semiconductors are connected to the proper terminals of the battery and why no light is being produced if we reverse the battery connections. Concept introduction: LED is defined as energy as light when electrons and holes combine in the p-n junction of a diode under a forward bias because of an electronic transition from the conduction band to the valence band. To determine: Why an LED produces light only when the n- and p-type semiconductors are connected to the proper terminals of the battery and why no light is being produced if we reverse the battery connections.
