Question

Four capacitors are connected as shown in figure. The equivalent capacitance between A and B is

  1. 4 muF    
  2. 0.25 muF    
  3. 0.75 muF    
  4. 1.33 muF    

The correct answer is: 1.33 muF


    fraction numerator 1 over denominator C subscript s end subscript end fraction equals fraction numerator 1 over denominator 1 end fraction plus fraction numerator 1 over denominator 1 end fraction plus fraction numerator 1 over denominator 1 end fraction equals 3
    C subscript s end subscript equals fraction numerator 1 over denominator 3 end fraction
    Capacitance between A and B
    C subscript p end subscript equals fraction numerator 1 over denominator 3 end fraction plus 1
    fraction numerator 4 over denominator 3 end fraction mu F equals 1.33 mu F
