Can I use Kirchoff's voltage rule to find the voltage across a charged capacitor? I don't really have a concrete.

Discussion Overview
The discussion revolves around the application of Kirchoff's Voltage Rule (KVL) to determine the voltage across a charged capacitor. Participants explore the theoretical and practical implications of using KVL in this context, with a focus on circuit analysis.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- Some participants question whether KVL can be applied to find the voltage across a charged capacitor, indicating a lack of concrete understanding.
- Others argue that KVL is applicable, noting that the voltage across the capacitor can be determined since one plate is positive and the other is negative, leading to a net sum of zero.
- A participant suggests that while it may not be intuitive, applying KVL and Kirchhoff's Current Law (KCL) strictly will yield the correct answer, and encourages looking at worked examples for better understanding.
- One participant humorously comments on the tone of the advice given, comparing it to a religious doctrine but acknowledges the evidence supporting the application of KVL.
- A brief affirmation of the validity of Kirchoff's Rules is mentioned, though without further elaboration.
Areas of Agreement / Disagreement
Participants express differing views on the intuitiveness and applicability of KVL to charged capacitors, indicating that there is no consensus on the initial understanding of the rule's application in this scenario.
Contextual Notes
Some assumptions about the circuit configuration and the nature of the capacitor are not explicitly stated, which may affect the applicability of KVL in different contexts.
