Three capacitors of capacitances 1 muF, ...

Three capacitors of capacitances `1 muF, 2 muF`, and `2 muF`, are cahrged up to the potential difference `30 V, 10 V`, and `15 V`, respectivly. If terminal `A` is connected with `D C` is connected with E and F is connected eith B, the find the charge flow in the ciruit and the final charge on the capacitors.
.

Text Solution

Verified by Experts

Let charge flow is q. Now applying kirchhoff's voltage low
`-((q-20))/(2)-((30+q))/(2)+(30-q)/(1)=0`
`-2q=-25`
`q=12.5 mu C`
Final charges on plates
