Homework Statement
A parallel-plate air capacitor is made by using two plates 18 cm square, spaced 3.5 mm apart. It is connected to a 3-V battery.
What is the capacitance?
Homework Equations
C = εo(A/d)
The Attempt at a Solution
εo = 8.854e-12
A = .18 m
d = .0035 m
C = εo (.18/.0035) = 4.55348571e-10 F
This is coming up as the wrong answer. I have no idea what I'm doing wrong.
