SUMMARY

In the discussion regarding adding voltages in parallel using diodes, it is established that you cannot achieve this due to the behavior of diodes under reverse bias conditions. Specifically, when one diode is reverse biased, it prevents current flow, resulting in a voltage output of 6V from the other diode. The superposition theorem is not applicable in this scenario, confirming the impossibility of adding voltages in parallel with diodes.

PREREQUISITES
  • Understanding of diode behavior, particularly reverse bias conditions
  • Familiarity with voltage concepts in electrical circuits
  • Basic knowledge of the superposition theorem in circuit analysis
  • Experience with circuit diagrams and voltage measurements
NEXT STEPS
  • Research the characteristics of diodes, focusing on forward and reverse bias operations
  • Study the superposition theorem and its applications in circuit analysis
  • Explore alternative methods for combining voltages in circuits, such as using operational amplifiers
  • Learn about practical applications of diodes in voltage regulation and protection circuits
USEFUL FOR

Electrical engineers, electronics students, and hobbyists interested in circuit design and analysis involving diodes and voltage behavior.

I'm sure you can't but I don't really see why not. Its been ages since I've done anything like this and I just wondered, I can't think of a way to varify it like I don't think you can use superposition theorem.

My question is shown in tha attatched picture.

Thanks very much.

you will get 6V because the top diode will be reversed biased.
 
Ofcourse! Simple and beautiful explanation.
