Web1 de nov. de 2024 · When reverse biased, an ideal diode can be replaced with infinite resistance, i.e. open circuit. Explanation: Given forward resistance of the diode as 50 Ω, and reverse biased resistance as infinite (open circuited). For the given voltage source configuration, the diode connected in series with 50 Ω resistance will be reverse biased. WebThere are two operating regions and three possible “biasing” conditions for the standard Junction Diode and these are: 1. Zero Bias – No external voltage potential is applied to the PN junction diode. 2. Reverse Bias – The voltage potential is connected negative, (-ve) to the P-type material and positive, (+ve) to the N-type material ...
