(a) Find the equivalent capacitance, and the energy contained in this equivalent capacitor.

equivalent capacitance=

µF

total energy stored=

(b) Find the energy stored in each individual capacitor.

energy stored in C1 J

energy stored in C2

**Damon**, Friday, January 27, 2012 at 11:19amThe charge is the same on both

Q = C V

so C1V1 = C2 V2

V2 = (C1/C2)V1 and V1 + V2 = 21

let C1 = 27*10^-6

let C2 = 35*10^-6

then C1/C2 = .77

then V2 = .77 V1

1.77 V1 = 21

V1 = 11.9 volts

V2 = 9.1 volts

I think you can take it from there
