How come when you reverse a diode the current/voltage? is zero?

Click For Summary
SUMMARY

The discussion centers on the behavior of diodes when reverse-biased, specifically why current and voltage are zero in this state. Participants reference the Wikipedia page on semiconductor diodes for foundational knowledge but express difficulty in articulating the concept in simple terms. The conversation highlights the importance of understanding P-N junctions, even if not yet covered in their syllabus. The need for clear explanations in layman's terms is emphasized, particularly for educational purposes.

PREREQUISITES
  • Understanding of semiconductor physics
  • Basic knowledge of diode operation
  • Familiarity with P-N junction theory
  • Graph interpretation skills related to electrical components
NEXT STEPS
  • Research the principles of P-N junctions in diodes
  • Study the I-V characteristics of diodes
  • Learn about reverse biasing in semiconductor devices
  • Explore practical applications of diodes in electronic circuits
USEFUL FOR

Students studying electronics, educators teaching semiconductor theory, and anyone seeking to understand diode functionality in circuits.

Hi I have been looking through my book, and even online for the answer because I don't understand why this happens, but I can't find the proper answer anywhere...can someone help me? Thanks.
 
Physics news on Phys.org
ok you will never need to know why its is the case until you do it as a job or do it at uni you do whoever have to recognise the graph odd but true.(Uk only)
 
Haha thanks but my teacher wants us to find out...and I read something like what wikipedia says but that is not the answer I'm suppose to have I already asked him :S.
 
if you are in the Uk get a copy of the sylabus and wave it in his face saying you don't need to know it sorry its my only anser.
 
Haha, no I'm not actually. I think he wants us to explain it in ENGLISH though, you know simply, because we haven't learned anything about P-N stuff yet...
