Two condensers of capacity C and 2C are connected in parallel and these are charged upto V volt. If the battery is removed and dielectric medium of constant K is put between the plates of first condenser, then the potential at each condenser is
As we have learned
Parallel Grouping -
- wherein
Initially Equivalent capacitance of the system
Total charge Q= (3C)V
Finally Equivalent capacitance of the system
Hence common potential
