Known Quantities:

Q1= 8.6 In the circuit below, consisting of a battery and several capacitors, some quantities are known and some are not. The capacitors were completely uncharged before the battery was attached and we are considering the static situation. (Be sure to keep at least 3 sig. figs. in your answer for all parts of this problem.) What is the potential difference across C1? V1 = What is the potential difference across C2 ? V2 = What is the potential difference across C3 ? V3 = What is the charge Q3 on capacitor C3? Q3 =

Explanation / Answer

1)Q1/C1=1.012 volts

2)sqrt(2*W/C2)=2.135 volts

3)as C2 and C3 are in parallel. voltage across C3 is same as C2=2.135 volts

4)charge on parallel combination of C2 and C3 is equal to charge on C1.

so if charge on C2 is q2, then charge on C3 is Q1-q2.

so charge on C3=3.261*10^(-6) C
