Question

Referring to the figure below, the effective resistance of the network is

  1. 2r    
  2. 4r    
  3. 10r    
  4. 5 r divided by 2    

The correct answer is: 5 r divided by 2


    Reffective=r plus fraction numerator 3 r over denominator 2 end fraction equals fraction numerator 5 r over denominator 2 end fraction
