Question

Five identical parallel conducting plates each of area A have separation ‘d’ between successive surfaces. The plates are connected to the terminal of a battery as shown in the fig. The effective capacitance of the circuit is

  1. fraction numerator A epsilon subscript 0 end subscript over denominator 4 d end fraction    
  2. fraction numerator 4 A epsilon subscript 0 end subscript over denominator d end fraction    
  3. fraction numerator A epsilon subscript 0 end subscript over denominator 3 d end fraction    
  4. fraction numerator 3 A epsilon subscript 0 end subscript over denominator 4 d end fraction    

The correct answer is: fraction numerator 4 A epsilon subscript 0 end subscript over denominator d end fraction
