Question

In the arrangement of resistances shown below, the effective resistance between points A and B is

  1. 20 capital omega    
  2. 30 capital omega    
  3. 90 capital omega    
  4. 110 capital omega    

The correct answer is: 20 capital omega


    By the concept of balanced Wheatstore bridge, the given circuit can be redrawn as follows

    Þ R subscript A B end subscript equals fraction numerator 30 cross times 60 over denominator left parenthesis 30 plus 60 right parenthesis end fraction equals 20 capital omega
