Question

In a circuit shown in figure, the potential difference across the capacitor of 2 F is

  1. 8 V    
  2. 4 V    
  3. 12    
  4. 6 V    

The correct answer is: 4 V


    therefore fraction numerator 1 over denominator C subscript s end subscript end fraction equals fraction numerator 1 over denominator 2 end fraction plus fraction numerator 1 over denominator 1 end fraction equals fraction numerator 3 over denominator 2 end fraction
    C subscript s end subscript equals fraction numerator 2 over denominator 3 end fraction F
    Q equals C subscript s end subscript V equals fraction numerator 2 over denominator 3 end fraction cross times 12 equals 8 C
    V subscript 1 end subscript equals fraction numerator Q over denominator C subscript 1 end subscript end fraction equals fraction numerator 8 over denominator 2 end fraction equals 4 V
