Electricity and Magnetism Question

Click For Summary
SUMMARY

This discussion addresses two key questions in Electricity and Magnetism (E&M): the visual representation and equations related to coaxial resistors and capacitors, and the calculation of self-energy for a charged sphere. Users are directed to perform a Google search for diagrams and specifications of coaxial components, while the calculation of self-energy is referenced in Feynman Lectures Volume II, chapter 8-1, which provides a comprehensive explanation. The conversation emphasizes the importance of understanding both theoretical and practical aspects of these concepts.

PREREQUISITES
  • Understanding of coaxial resistors and capacitors
  • Familiarity with self-energy concepts in electrostatics
  • Knowledge of Feynman Lectures, specifically Volume II
  • Basic skills in conducting online research for technical specifications
NEXT STEPS
  • Research coaxial resistor and capacitor diagrams and specifications
  • Study the calculation of self-energy in charged spheres using electrostatic principles
  • Read Feynman Lectures Volume II, chapter 8-1 for detailed explanations
  • Explore laboratory methods for measuring energy in charged spheres
USEFUL FOR

Students and professionals in physics, electrical engineering, and anyone seeking to deepen their understanding of Electricity and Magnetism concepts, particularly in relation to coaxial components and energy calculations.

I have a couple of questions in E&M.

a)Can anyone tell me what a coaxial resistor and a coaxial capacitor looks like? (Approx Diagram) Because I am not sure which equations apply to them since I am not sure what they look like.
b)How do I find a self energy of a charged sphere? Split it into 2 parts and bring it together? Not sure on this one, if someone can help, thnx.

b) Do you mean how do you measure (in the lab) the energy in a charged sphere?

Or do you mean how do you calculate the energy in a charged sphere?

There is a good discussion on calculating the energy of a charged sphere in Feynman Lectures Volume II chapter 8-1.

a) Just do a Google sreach for the coaxial caps and resistors. You can find the complete specs from most vendors.
