Capacitance between two parallel wires not straight

AI Thread Summary
Calculating capacitance between two parallel wires that are not straight, such as parabolic wires, requires the use of calculus. The discussion emphasizes the need for a mathematical approach to address this general question. Participants confirm that the forum is suitable for such inquiries. The original poster expresses a willingness to learn and acknowledges potential posting errors. Understanding calculus is essential for solving this type of problem effectively.

Hi,

I would like to know how to calculate capacitance between two wires which are parallel but not necessarily straight.for instance the two wires might be parabolic..I would like to calculate for such general structures.i.e) two parallel wires that are not necessarily straight.

Thanks in advance

You would use calculus.

Is this a general question, or do you have a specific homework exercise in mind?

Hi,

This is a general question.am sorry if I have posted in the wrong area.I ll read about the forum and post where it is supposed to be posted.

Thanks.
 
This forum is appropriate for your general question. Have you studied caculus in maths classes?
 
Susskind (in The Theoretical Minimum, volume 1, pages 203-205) writes the Lagrangian for the magnetic field as ##L=\frac m 2(\dot x^2+\dot y^2 + \dot z^2)+ \frac e c (\dot x A_x +\dot y A_y +\dot z A_z)## and then calculates ##\dot p_x =ma_x + \frac e c \frac d {dt} A_x=ma_x + \frac e c(\frac {\partial A_x} {\partial x}\dot x + \frac {\partial A_x} {\partial y}\dot y + \frac {\partial A_x} {\partial z}\dot z)##. I have problems with the last step. I might have written ##\frac {dA_x} {dt}...
Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'
I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
