Today our physics teacher teach us how to find resistance of a network of resistance that is messed to heavily(example all sides of a cube are resistance find resistance). Ok those are very good methods, but it seems that they are not result of experiments done by genius persons it seems that they are derived from Kirchoff's laws of loops. Can you please tell me the proof or something like this for their tricks these short cut tricks.
these short ct tricks are After all i hope you will not reply so. thanks for reading. make reply if you know anything about it.double thanks to repliers.

Does non of you know it's answer??
If their is any problem understanding question then tell me i will try to make it clear.

explanation for 1(a) let us assume that there is different current in upward upper and lower part of circuit. Now just reverse the direction of the circuit i mean upper part in lower and lower in upper. So the current slowing in upper part will now the current in lower part and current flowing in lower part willl in upper part. BUT the circuit is same as it was before reversing. So here arise contradiction which can killed if and only current in upper and lower region will same. 1(b) still now i have no idea for this. 2(a) It is much similar to 1(a) but in this case we require to revert the direction of current. If we take current different then contradiction will arise which can be cured only by taking current similar. 2(b) It is derivative of 2(a) 2(c) doesn't get; 2(d) One more thing that i can't explain. hey friends please help yar;Tell me something that how it can.

short cut tricks to find resistance of large/messed resistance's network.Look at the following circuit and ask yourself if the equivalent resistance between A and B is unaffected by removing R_{s}. go well

How you can explain all the phenomena by one example. It's particular case.
