Condenser A has a capacity of 15 F when it is filled with a medium of dielectric constant 15. Another condenser B has a capacity 1 F with air between the plates. Both are charged separately by a battery of 100V. after charging, both are connected in parallel without the battery and the dielectric material being removed. The common potential now is
400V
800V
1200V
1600V
As we have learned
Parallel Grouping -
- wherein
Charge on capacitor A is given by
Charge on capacitor B is given by
Capacity of capacitor A after removing dielectric
Now when both capacitors are connected in parallel their equivalent capacitance will be Ceq = 1+1 =
So common potential
Option 1)
400V
Option 2)
800V
Option 3)
1200V
Option 4)
1600V
