A capacitor of 1 µF withstands a maximum voltage of 6 kilovolt while another capacitor of 2 µF withstands a maximum voltage of 4 kilovolt. If the two capacitors are connected in series, the system will withstand a maximum voltage of –

1.  2 kV                 

2.  4 kV 

3.  6 kV                 

4.  9 kV

Combination of capactiors

4. For series combination Cs=C1C2C1+C2   Cs=23 μF

    When connected in series the maximum charge that can flow through the combination equals

    the lower value of charge accommodated by the first capacitor i.e. 6000 µC

           Q1= 6000 μC  and 8000 μC                Vs=Q1Cs=6000 μC2/3 μC      Vs= 9 kV
