Homework Statement
We have a resistor grid with 6x6 squres. ( figure below) If we know the voltage between ##O## and ##A##, what is the voltage between:
##a) O## and ##B##
##b) C## and ##D##
##c) E## and ##F##
Every side has the same resistance.
Attempt for solution:
Because of the symmetry of the circuit , the equivalent circuit looks like this:
Now every resistance is half its initial value because of the parallel connection.
From here on I am stuck . I mean I don't really like applying kirchhoff's laws in situations like this. So I checked the solution and there the author connected the grid like this "from symmetry":
And after this:
I don't really think that these points that the author connected are equipotential especially in the first and third picture of his solution...
Am I right?
