`T` Two capacitors of capacitances `1 muF` and `2 muF` are charged to potential differnces `20 V` and `15 V` as shown in. If terminals B and C connected together and terminals A and D are connected with the positive and negative ends of the battery, respectively, then find the final charges on both the capacitors.
.

Explanation

Now applying kirchoff voltage law
`(-(20+q))/(1)-(30+q)/(2)+30=0`
`-40-2q-30-q=-60`
`3q=-10`
Charge flow `=-10//3 mu C`.
Charge on capacitor of capacitance `1mu F=20+q=(50)/(3) mu C`
Charge on capacitor of capacitance `2mu F=30+q=(80)/(3) mu C`
