1. The problem statement, all variables and given/known data http://[ATTACH=full]199661[/ATTACH] [B]2. Relevant equations[/B] [B]3. The attempt at a solution[/B] It has becomes a P type semi conductor due to the fact that there is more acceptor than donor. From definition , forward bias is the direction of easy current flow while reverse bias is in the direction of little to no current flow. I check online and it say that when it is in reverse bias , voltage at the cathode (P type junction) is higher but why?
