Question

For the system of capacitors shown in the the figure below (Figure 1), a potential difference of 24.0V is maintained across ab.

A) What is the equivalent capacitance of this system between a and b ?

C=       nF

B) How much charge is stored by this system?

Q=      nC

C) How much charge does the 6.5nFcapacitor store?

Q=      nC

D) What is the potential difference across the 7.5nFcapacitor?

V=       V

Please show your work so I can understand how to do these problems. Thanks.

Explanation / Answer

18nF,30nF,10nF ARE IN SERIES

1/C1 = (1/18)+(1/30)+(1/10)

C1 = 5.29 nF

C1 , 7.5nF and 6.5nF arein parallel

Cnet = 5.29+7.5+6.5 = 19.29 nF

B) Q = Cnet*V = 19.29*10^-9*24 = 462.96 nC

C) Q = 6.5*10^-9*24 = 156 nC

D)V= 24Volts
