Three uncharged capacitors of capacitance C1 = 1micro F, C2 = 2 micro F and C3 = 3 micro F are connected as shown in the figure to one another and to points A, B and D. Potential at A = 10V, at B= 25V and at D = 20V. Determine the potential at O

Question

Eshan · Answer

Let the potential at point O be . From Kirchoff&rsquo;s voltage law, the current passing from B to O will be divided into branches OA and OD. Hence the charge aquired on the branch BO will be equal to that on OD and OA summed together.

Khimraj · Answer

V a = 10V V b = 25V V c = 20V V = ? Applying KCL Q a + Q b + Q c =0 1(10 -V) + 2(25 – V) + 3(20 -V) = 0 120 -6V = 0. So V = 20V Hope it clears.
