Member advised to use the homework template for posts in the homework sections of PF.
I have been studying the method of symmetry from some days, which essentially reduce the effort needed for the evaluation of equivalent resistances. My textbook states:
Points having symmetrically located about initial and final points have the same potentials.So, the resistances between these points can be ignored.

Okay, fine. Problems get solved,but I have some questions regarding this.
Please help me. If you can, please recommend some JEE Physics Textbooks too.
Thanks!

Okay, fine. Problems get solved,but I have some questions regarding this.
- Why does the method of symmetry work?
- Does the method only apply for resistors of equal value/magnitude?
- If yes, then how do we deal with asymmetrical circuit of resistors, say, in a cube?
- And most essentially, how do we define symmetry?
Please help me. If you can, please recommend some JEE Physics Textbooks too.
Thanks!
