Questions In Electricity And Thermal Physics

Click For Summary

Discussion Overview

The discussion revolves around questions related to electricity and thermal physics, specifically focusing on the behavior of filament lamps, the structure of electric cells and batteries, and the chemical reactions occurring within batteries. The scope includes conceptual understanding and application of physics principles in these areas.

Discussion Character

  • Homework-related
  • Conceptual clarification

Main Points Raised

  • One participant questions how electrons return to their original energy levels in a filament lamp while it continues to emit light and heat.
  • Another participant seeks information on the structure of electric cells and batteries.
  • A participant wonders why chemical reactions in batteries occur only when connected to a component, questioning if reactions happen when disconnected.
  • Responses suggest that participants should conduct background research and attempt to answer the questions themselves before seeking help.

Areas of Agreement / Disagreement

There is no consensus on the answers to the questions posed, and multiple viewpoints exist regarding the approach to finding solutions. Some participants emphasize self-research and understanding before asking for assistance.

Contextual Notes

Participants have not provided detailed explanations or definitions, and there are assumptions regarding prior knowledge of physics concepts that may not be universally shared.

Who May Find This Useful

This discussion may be useful for students preparing for exams in electricity and thermal physics, as well as those seeking clarification on related concepts.

Hi

Within one month and a half I will be taking an exam in this section of physics and I need answers for some questions or in fact lots of questions:

que 1 / when a filament lamp glows that means it has been heated and as I understood from physics that light is emitted when electrons come back to their original energy levels what i am wondering is how these electrons come back and the heating process is continueing or the energy is still giving??

ques 2 / Can any of you provide me the structure of an electric cell??And the same for a battery?

que 3 / It is said that energy inside a battery is produced by the chemical reaction and what I am wondering is why the chemical reaction is only taking place when the battery is connected to a component?Or I am mistaken, the chemical reaction is taking place even if the battery is not connected??

Looking forward to receiving answers.

Hey come on gays help me in answering these questions...
 
:bugeye: :frown: :bugeye: :frown: :eek: :eek:
 
Looking forward to receiving answers.

This is not an "answer" service. Try the questions and we can help you through them. Searching Google is great for finding facts.
 
Start at wikipedia.org, and do searches and some reading on subjects like batteries, light bulbs, black body radiation, electron orbitals, light, etc. That will get you far, my friend.

Then after you do that background work, please feel free to post specific questions here (showing your work up to the point where you are stuck or confused). Welcome to the PF.
