Explanation / Answer

a) 1/C = 1/150 + 1/120 = 4/600 + 5/600 = 9/600

C = 600/9 nF

Q = CV = 600.0E-9/9*46=3.07E-6 C = 3.07 uC

b) things in series have the same charge

both will be 3.07 uC

c) E = 1/2 C V^2 = 0.5*(600.0E-9/9)*46^2= 7.05E-5 J = 70.5 uJ

d)U150 = Q^2/(2 C) = 3.07E-6^2/(2*150.0E-9)=31.4 uJ

U120 nF = 3.07E-6^2/(2*120.0E-9)=39.3 uJ

e) V150Nf = Q/C = 3.07E-6/150.0E-9=20.47 V

V 120nF = 3.07E-6/120.0E-9=25.58 V
