Finding equivalent resistance
Hi, in example 27, I don't understand how the current through the middle 5 ohm resistor is assumed to be 2x-i, I know that we can use KCL for the junction but it assumes either i-x for the top right 10 ohm resistor or 2x-i for the middle 5 ohm one, how can these assumptions be explained? Is it because of any type of symmetry? Any other way to do these kind of problems? Thank you

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Symmetry only
And dw they mostly ask symmetrical questions
If by chance they do ask non symmetrical use nodal analysis
Thank you, nodal analysis means to assume voltages and solve right
just use delta star conversion for net resistance
thanks
