Can you explain the answer of this question below:
Twelve 6 Ω resistor are used as edge to form a cube.The resistance between two diagonally opposite corner of the cube is
  • A:
    5/6 Ω
  • B:
    6/5 Ω
  • C:
    5 Ω
  • D:
    6 Ω
The answer is c.

Can you explain the answer of this question below:Twelve 6 Ωresis...
Current i will be split into 3 branch currents. 

Since the resistance is same (i.e. 6 Ω), Current in each branch will be i/3.

This i/3 current will in turn split into 2 branch currents each of value i/6.

The current between 2 diagonally opposite side will be composed of two i/3 currents and one i/6 current.

(i/3) + (i/3) + (i/6) = 5i/6 ==>(V/R)

V = 5i; Req= V/i = 5i/i = 5Ω
