Questions In Electricity And Thermal Physics

Click For Summary
SUMMARY

The forum discussion centers on fundamental concepts in electricity and thermal physics, specifically regarding filament lamps, electric cells, and batteries. The user seeks clarification on the mechanisms of electron behavior in filament lamps, the structure of electric cells and batteries, and the conditions under which chemical reactions occur in batteries. Participants emphasize the importance of conducting preliminary research using resources like Wikipedia and suggest that users post specific questions after attempting to understand the material independently.

PREREQUISITES
  • Understanding of basic electricity concepts, including voltage and current.
  • Familiarity with thermal physics, particularly black body radiation.
  • Knowledge of atomic structure, specifically electron orbitals.
  • Basic chemistry principles related to chemical reactions in batteries.
NEXT STEPS
  • Research the principles of black body radiation and its relation to light emission.
  • Study the structure and function of electric cells and batteries, focusing on electrochemical reactions.
  • Learn about the behavior of electrons in conductive materials and their role in thermal processes.
  • Explore the differences between series and parallel battery connections and their impact on chemical reactions.
USEFUL FOR

Students preparing for exams in physics, educators teaching electricity and thermal physics, and anyone interested in the practical applications of batteries and electric circuits.

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...

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.
