Their current varies exponentially according to the Shockley equation, and four of them make up a bridge rectifier.
Some types of this device exhibit negative resistance at higher voltages. Their current varies exponentially according to the Shockley equation, and four of them make up a bridge rectifier. One type achieves rapid switching by replacing a p-type semiconductor with a metal contact, while another type allows for reverse bias operation because of its reduced breakdown voltage; those are the Schottky and Zener types. Consisting of a PN-junction, they allow current to pass in only one direction. For 10 points, name these circuit components, one type of which is "light-emitting."
