Question

The figure shows a tetrahedron, each side of which has a resistance r

Choose the correct statement(s) related to the resistance between any two points

  1. R subscript A B end subscript equals R subscript B D end subscript equals R subscript B C end subscript equals R subscript C D end subscript equals R subscript C A end subscript equals R subscript A D end subscript    
  2. R subscript A B end subscript equals R subscript A C end subscript equals R subscript A D end subscript equals R subscript B D end subscript equals R subscript B C end subscript not equal to R subscript C D end subscript    
  3. R subscript C D end subscript is the least    
  4. R subscript A B end subscript equals R subscript A C end subscript equals R subscript B C end subscript text  and  end text R subscript C D end subscript equals R subscript A D end subscript equals R subscript B D end subscript    

The correct answer is: R subscript A B end subscript equals R subscript B D end subscript equals R subscript B C end subscript equals R subscript C D end subscript equals R subscript C A end subscript equals R subscript A D end subscript
