Question

If V subscript A B end subscript equals 4 V in the given figure, then resistance X will be

  1. 5 capital omega    
  2. 10 capital omega    
  3. 15 capital omega    
  4. 20 capital omega    

The correct answer is: 20 capital omega


    V subscript A B end subscript equals 4 equals fraction numerator 5 X plus 2 cross times 10 over denominator X plus 10 end fraction Þ X equals 20 capital omega
