Question

The potential difference between points A and B of adjoining figure is

  1. fraction numerator 2 over denominator 3 end fraction V    
  2. fraction numerator 8 over denominator 9 end fraction V    
  3. fraction numerator 4 over denominator 3 end fraction V    
  4. 2 V    

The correct answer is: fraction numerator 4 over denominator 3 end fraction V


    The given circuit can be redrawn as follows

    For identical resistances, potential difference distributes equally among all. Hence potential difference across each resistance is fraction numerator 2 over denominator 3 end fraction V comma and potential difference between A and B is fraction numerator 4 over denominator 3 end fraction V.
