    Rules Voltage
AI Thread Summary
The discussion revolves around confusion regarding the application of Kirchhoff's voltage law (ƩV = 0) versus using the formula V = Q/C for finding potential in capacitors. The user notes that while using V = Q/C yielded correct answers for certain problems, the later introduction of Kirchhoff's rules led to a situation where the voltage values summed to zero. This raises questions about when Kirchhoff's rules should be applied, especially since both types of problems involve closed-loop circuits. The user seeks clarification on the consistent application of these principles in circuit analysis. Understanding when to use each method is crucial for accurately solving circuit problems.

I'm getting confused with the problems that ask you to find potential and when to use the rule that the sum of all the V = 0.
There were a lot of questions in my physics book that ask to find a potential in each capacitors and when i was doing those, i just used V = Q/C instead of Kirchhoff's rules (and the answers were right). In those questions, the values of V didn't add up to 0.
But then later, the book started using that ƩV = 0... and now the V values actually adds up to 0... and I'm really confused when Kirchhoff's rules apply...
The book says it applies to all closed-loop circuits. but the ones that asked to find potential with V = Q/C were also closed-loop circuits. mmm...
Can anyone please explain this to me? :O

Im sure,and confident,that all closed loop circuits you solved using Q=CV, or any other formula in the word, The sum total of potential changes were ALWAYS Zero.Please post such an example,and people will be happy to clarify
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
