For the system of capacitors shown in the figure below. a potential difference of 24.0 V 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 6.5 nf capacitor store? what is the potential Difference across the 7.5 nf capacitor?

Explanation / Answer

A)What is the equivalent capacitance of this system between a and b ?
Capacitors in series combine as follows: 1/[1/18e-9 + 1/30e-9 + 1/10e-9] = 5.3nF
Capacitors in parallel combine as follows: 7.5e-9 + 5.3e-9 + 6.5e-9 = 19.3nF <---- A)
B)How much charge is stored by this system?
Q=CV = 19.3nF*24 = 463.1 nC
C)How much charge does the 6.5nF capacitor store?
6.5nF* 24 = 156 nC
D)What is the potential difference across the 7.5nF capacitor?
24V
