I am really confused , i can't figure out which of them are in parallel and which are in series !!!
Can you help me to find a way to figure this out ...

Am I missing the 80Ω resistor?Here is one way.
Very good catch.Am I missing the 80Ω resistor?
Huh? It DOES connect with the 25Ω resistor. Directly.Ok , i think i solved it !!
Thank you all for your help especially studiot
It took me a while to figure it why the 4R resistor doesnt connect with the 25 ohm but i think i got it....
There are a lot of good things you can still do with this problem, too.Do you guys have any other circuit that i can solve?? I really need the practice and i will post the answer here to confirm it !!
Let's color the key nodes and see that they all still connect to the same resistors.Thanks for your time WBahn !!
I can't fully understand this: The 25 ohm is connected with the wire that leads to the 80 ohm and the 4R , how can we skip the 4R connection in the redrawn ?? and then connect both R and 4R to the 20 ohm (since in my mind the current in the original design flows to the R not the 4R but in the redrawn flows to both...)
I hope that you understand what i am trying to say
Here's a circuit from another forum.Do you guys have any other circuit that i can solve?? I really need the practice and i will post the answer here to confirm it !!
You think so?"...there is a good chance that you will make a mistake in calculating at least one of these effective resistances.""
This doesn't seem quite right. Suppose we have 10Ω and 100Ω in parallel. The parallel combination can be smaller than 50Ω.But it also cannot be any smaller than half the larger resistor, either,.
That was a typo - typed smaller when I meant to type larger. My thought at the time was that the upper bound is the smaller of the smaller resistor or half the larger resistor, but that seemed a bit convoluted, so I put it into two sentences... and messed it up.This doesn't seem quite right. Suppose we have 10Ω and 100Ω in parallel. The parallel combination can be smaller than 50Ω.
