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. Find the potential difference across each capacitor. Express your answers using two significant figures separated by a comma.

Explanation / Answer

a)

C=150*220/(150+220)

C=89.2 nF

Q=CV =89.2*10^-9*38

Q=3.39*10^-6 C or 3.39uC

b)

Q1=Q2=Q=3.39uC

c)

E=(1/2)CV^2 =(1/2)*89.2*10^-9*38^2

E=6.44*10^-5 J

d)

E(150 )=(Q^2/2C =(3.39*10^-6)^2/2*150*10^-9=3.83*10^-5 J

E(220)=(3.39*10^-6)^2/2*220*10^-6=2.61*10^-5 J

e)

V1=Q1/C1 =22.6 V

V2=Q2/c2 =15.4 V
