Answered: the case of pn junction of the same… bartleby

WebA forward-biased PN junction conducts a current once the barrier voltage is overcome. The external applied potential forces majority carriers toward the junction where recombination takes place, allowing current flow. A reverse-biased PN junction conducts almost no current. The applied reverse bias attracts majority carriers away from the junction. WebMar 18, 2013 · When the p-n junction is reverse biased, the barrier resistance is increased, so little or no electron current flows. When forward biased, the barrier resistance is …
