Click For Summary

Discussion Overview

The discussion revolves around the behavior of capacitors in circuits with DC and AC sources, specifically focusing on energy transfer and work done during the charging process. It touches on fundamental concepts in electrical circuits and the nature of conduction.

Discussion Character

  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant asserts that in a DC circuit with a capacitor, there are no energy losses during charging due to the absence of conduction, questioning if the same applies to an AC source.
  • Another participant challenges this assertion by asking how a capacitor can charge without conduction, suggesting a misunderstanding of the charging process.
  • A participant acknowledges that work is indeed done by the source during the charging process, as charge is moved to the capacitor's plates, indicating a realization of their earlier misconception.
  • Further comments reflect on the nature of learning, suggesting that initial misunderstandings can lead to deeper insights.

Areas of Agreement / Disagreement

Participants express differing views on the initial claim regarding energy losses and conduction in DC and AC circuits. There is no consensus reached, as some participants clarify and refine their understanding while others maintain their original positions.

Contextual Notes

The discussion highlights potential confusion regarding the concepts of conduction and work done in charging capacitors, with no resolution on the implications for AC sources. Assumptions about ideal conditions in circuits are also present but not fully explored.

hello,

a simple question: a circuit with a DC source and a capacitor (assume no voltage loses due to the cables etc..)
there wille be nog energy loses during the charging of it, because there's no conduction in the whole circuit, so no work is done by de DC source

now assume a AC source, in this case also no work is done by the source ?

is this all correct ?

How does a capacitor get charged with no conduction of electricity? I think you are confusing the final static equilibrium system with the process of charging.
 


yes indeed, during the process of charging work is done by the source, because charge has been moved to the capacitors plate !

stupid tginking of me ! :blushing:

:rolleyes: I'm pretty sure stupid thinking, almost always precedes smart thinking.:smile:
 


but those thing are quit fundamental...
but you're rigth great inventions were made by some crazy ideas

htank you !
