For the system of capacitors shown in the the figure below(Figure 1) , a potential difference of 25.0V is maintained across ab. What is the equivalent capacitance of this system between a and b? How much charge is stored by this system? How much charge does the 6.50 nF capacitor store? What is the potential difference across the 7.50 nF capacitor?

Explanation / Answer

A) for centre branch 1/C = 1/18+1/30+1/10, C = 5.3nF, equivalent capacitance of this system between a and b = 7.5+5.3+6.5=19.3nF

B) V = Q/C, so Q = V*C = 25*19.3 = 482.5nC

C) 6.5*25 = 162.5nC

D) 25 V
