Three uncharged capacitors are connected...

Three uncharged capacitors are connected as shown in the figure. If potentials at point P, Q and R are maintained at 1V, 2V, 3V respectively, then potential at O becomes
.

Text Solution

Verified by Experts

The correct Answer is:
2.33
Let the potential at O be `V_(0)`, then `1(V_(0)-1)+2(V_(0)-2)+3(V_(0)-3)=0, (14)/(6)V=(7)/(3)`volt=2.33 V.
