That makes much more sense. In fact, I think that is the concept. It has just been given the wrong title. When we were made to solve the 3D cube problem, we used what you stated above. So do I. Especially when they seem so forced, like this one. The reason we're being taught shortcuts and...

Exactly! Which is why I wanted to know the reason.

Sure. The symmetry I'm referring to is the one in geometrical shapes, like a square or a rectangle. Consider this circuit: This circuit is symmetrical about the red line - a perpendicular bisector. I have been taught that since it is symmetrical about that line, the potential of each point...

I understand that. My question is: how does symmetry fit into this? What has a line of symmetry through a network of circuit elements got to do with the potential at different points along the line? I understand that if the potential of two points is the same, current will not flow between...

How is symmetry used to solve electrical circuits? I have seen several problems in books in which currents in two resistors are said to be equal due to 'symmetry'. That is a concept that I fail to understand and thus cannot apply. In class, we were shown a few circuit diagrams which were...

I'm a passout from school taking a gap year. I find the concept of conservation of momentum exceedingly difficult. Each question - and sometimes each part of a question, if a question has different parts - requires us to choose different systems each time. I look at the solution, and think I...
