## Homework Statement

Three capacitors, with capacitances C1 = 4.0 μF, C2 = 3.0 μF, and C3 = 2.0 μF, are connected to a 24 -V voltage source, as shown in the figure. What is the charge on capacitor C2?

a) What is the equivalent capacitance of the three capacitors ?

b) What is the potential difference across C1 ?

c) What is the charge on C2 ?

d) What is the electrical energy stored on C3 ?

## Homework Equations

q=CV

Parallel share V

Series Share q

## The Attempt at a Solution

a) So I know that C2 and C3 are parallel so C23=5

Then, C23 and C1 and in series, so C

_{eq}=2.2μF

b) Find Charge of C1 and use that to find Potential Difference. V=5.2E-2V

c) Charge on C2 is 5.2E-2V / 3μF = 1.73E4C

d) U =.5*C*V^2 so U=5.76E-4J

Also, this isn't relevant but I don't think it justifies it's own post. How is W=VQ the same as W=EdQ? I appreciate any help
