Question

In the figure, three capacitors each of capacitance 6p F are connected in series. The total capacitance of the combination will be

  1. 9 cross times 1 0 to the power of negative 12 end exponent F    
  2. 6 cross times 1 0 to the power of negative 12 end exponent F    
  3. 3 cross times 1 0 to the power of negative 12 end exponent F    
  4. 2 cross times 1 0 to the power of negative 12 end exponent F    

The correct answer is: 2 cross times 1 0 to the power of negative 12 end exponent F


    C to the power of ´ end exponent equals C divided by n equals fraction numerator 6 cross times 1 0 to the power of negative 12 end exponent over denominator 3 end fraction equals 2 cross times 1 0 to the power of negative 12 end exponent F
