Question
The network shown in the figure below is assembled with uncharged capacitors X, Y,
and Z, with Cx 7 uF, Cy=8 μF, and Cz = 5 μF and open switches, S₁ and S2. A
potential difference Vab +120 V is applied between points a and b. After the network is
assembled, switch S₁ is closed for a long time, but switch S2 is kept open. Then
switch S₁ is opened and switch S2 is closed. What is the final voltage across capacitor X?
V₁ = +120 V
