Question

In the following circuit the equivalent resistance between A and B is

  1. fraction numerator 20 over denominator 3 end fraction capital omega    
  2. 10 capital omega    
  3. 16 capital omega    
  4. 20 capital omega    

The correct answer is: 16 capital omega


    According to the given figure A is at lower potential w.r.t. B. Hence both diodes are in reverse biasing, so equivalent, circuit can be redrawn as follows.
    Þ Equivalent resistance between A and B
    R = 8 + 2 + 6 = 16 capital omega.
