`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 Kirchhoff`s voltage law

or `(-(20+q))/1-(30+q)/2+30=0`
or `-40-2q-30-q=-60`
or `3q=-10`
Charge flow is `-10//3 muC`
Charge on capacitor of capacitance `1 muF` is `20+q=(50)/3muC`
Charge on capacitor of capacitance `2 muF` is `30+q=(80)/3muC`.
