- Homework Statement
- Twelve resistors form the edges of a cube as shown
in the figure. If the potential difference between
opposite corners A and A' is 18 V, find the equivalent
resistance between A and A'.(Figure is in 'Attempt at a Solution' section)
- Relevant Equations
- There are no equations in for this question.
By the use of symmetry, I have found that equal currents will flow through opposite edges like A-C and C'A', but still, the use of kirchhoffs current and voltage laws lead to four equations in four variables which I am not able to solve, neither I am sure that the four equations which I have created are independent since I have used symmetry in dividing currents.I have also tried using star delta conversion but its going too long. I think there should be some shorter method to solve this, can anyone please give a hint?(Not complete solution)
