Question

PART E) Find the potential difference across each capacitor.

For the capacitor network shown in the figure below Figure 1. the potential difference across ab is 240V. Find the total charge stored in this network. Express your answer using two significant figures. Find the charge on each capacitor. Express your answers using two significant figures separated by a comma. Find the total energy stored in the network. Express your answer using two significant figures. Find the energy stored in each capacitor. Express your answers using two significant figures separated by a comma.

Explanation / Answer

a)

equivalent capacitance

C=35+75=110 nF

Total charge

Q=CV =110*10^-9*240

Q=26.4 uC

b)

Charge on each capacitor

Q35=CV =35*10^-9*240=8.4 uC

Q75=75*10^-9*240=18 uC

c)

U=(1/2)CV2=(1/2)*(110*10^-9)*240^2

U=3.17 mJ

d)

U35=(1/2)*(35*10-9)*240^2 =1.01 mJ

U75=(1/2)*(75*10^-9)*2402=2.16 mJ

e)

V35=240 Volts

V75=240 Volts
