Answer:
  • On analyzing the direction of the potential difference applied to the circuit, the total potential difference will be V=12 kV+13kV=25kV.
  • This potential difference is divided by two capacitors, say C1=7mF and C2=3mF.
  • As they are connected in series due to the series polarity of the connected potential difference.

             begin mathsize 12px style Potential space difference space across space straight C subscript 1 space straight i. straight e space
left parenthesis straight V subscript 1 right parenthesis equals fraction numerator straight C subscript 2 over denominator space straight C subscript 1 plus space straight C subscript 2 end fraction cross times straight V equals 3 over 10 cross times 25
Potential space difference space across space straight C subscript 1 equals 7.5 space straight V

Similarly space for space
Potential space difference space across space straight C subscript 2 space straight i. straight e space
left parenthesis straight V subscript 2 right parenthesis equals fraction numerator straight C subscript 1 over denominator space straight C subscript 1 plus space straight C subscript 2 end fraction cross times straight V equals 7 over 10 cross times 25
Potential space difference space across space straight C subscript 2 equals 17.5 space straight V

end style
