Text Solution
Verified by ExpertsD
Let and
be the voltages across
and
capacitors respectively as shown in the figure. Then
As and
capacitors are series, charges on each is the same.
or
or
Substituting this value of in eqn. (i), we get
From eqn. (i)
Now they are disconnected and reconnected in parallel.
Let the potential difference across the combination be . Then
