Capacitance of the capacitor after inserting the dielectric

Click For Summary

Homework Help Overview

The discussion revolves around understanding the capacitance of a capacitor when a dielectric is inserted, particularly when the dielectric does not completely fill the space between the plates. Participants are exploring the implications of this setup in the context of their homework assignment.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • The original poster seeks foundational knowledge about capacitance and dielectrics, expressing uncertainty about the topic due to lack of instruction. Other participants provide links to resources and clarify that the position of the dielectric does not affect the capacitance result, prompting further questions about the implications of this information.

Discussion Status

The discussion is ongoing, with participants sharing resources and clarifying concepts. Some guidance has been offered regarding the relationship between the dielectric's position and the capacitance, but there remains some uncertainty from the original poster about how this applies to their specific problem.

Contextual Notes

The original poster indicates a lack of prior instruction on the topic, which may affect their understanding and approach to the problem. There is also a mention of a specific homework rule regarding the completeness of the dielectric filling the capacitor.

The Attempt at a Solution


Hi. My instructor gave me this problem as a homework. Actually he didnt teach us this subject. So what should i know to solve this question or from where can i study to this subject? Of course it would be great if someone solve the problem but i don't want to take your time, just need the info of this subject to learn the subject and solve the problem. Thanks..

Check this out. Then come back if you have questions. Note that the dielectric does not fill the space between plates completely. This needs to be taken into account.

Thanks for the answer. After i learned the subject, i solved the problem. Then i noticed my answer is the same with answer on the pdf. (check image) I think it is the same question by the way. Isn't it?

Yes, it is the same. Note that the exact position of the dielectric does not affect the result as long as the dielectric surfaces are parallel to the plates.

Im not sure i understood you. so does it change the result at my problem? Or you just said me that as an info? Sorry for my eng. Thanks btw you helped me a lot.
 
Just a point of information in case you see this again. The answer does not change,
