Question

We have a combination as shown in following figure. Choose the correct options :
                                     

Options

A.Total charge in this series combination is 600 μC
B.The potential difference between the plates of C1 is 30 V
C.The potential difference between the plates of C2 is 20 V
D.The potential difference between the plates of C3 is 40 V

Solution

                Ceq =
Total charge in this series combination is = × 90                  q = 600μC
Potential difference between the plate of C1 is = = = 30 V
Potential difference between the plate of C2 is = = = 20 V
Potential difference between the plate of C3 is = = = 40 V
