Please see attachment: two questions 12, 13 with their figures, thank you.
13. In figure 25-29, a potential difference of V = 100.0 V is applied across a capacitor arrangement with capacitances C1 = 10.0 uF, C2 = 5.00 uF, and C3 = 4.00 uF. If capacitor 3 undergoes electric breakdown so that it becomes equivalent to conducting wire, what is the increase in
(a) charge on capacitor 1
(b) the potential difference across capacitor 1?
It shows how to determine the charge and the potential difference across the capacitor in a certian circuit. The solution is detailed and was rated '5/5' by the student who originally posted the questions.
