## Homework Statement

An AA battery (1.5 V potential) is connected to a parallel-plate capacitor having 6.00cm-diameter plates spaced 4mm apart. How much charge does the battery move from one plate to the other?

## Homework Equations

V=Q/C
C=A$$\kappa$$$$\epsilon$$/d

## The Attempt at a Solution

Plugged in values:
C = (.03)2*(8.85*10-12)/.004 = 1.99*10-12
Q = 1.5V * 1.99*10-12f

Getting an incorrect answer for Q. Thoughts?

You forgot a factor of $\pi$ in the formula for area.
