(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Capacitance Problem

1. The problem statement, all variables and given/known data

A parallel-plate air capacitor is made by using two plates 16 cm square, spaced 4.7 mm apart. It is connected to a 12-Volt battery.

What is the capacitance?

2. Relevant equations

[tex]|C = \epsilon_r\epsilon_0\frac{A}{d}[/tex]

3. The attempt at a solution

Using:

[tex]\epsilon_r[/tex] = 1.00059

[tex]\epsilon_r = 8.85*10^{-12}[/tex]

A = 0.0016m

d = 0.0047m,

And inserting into the formula, I get:

[tex]|C = (1.00059)(8.85*10^{-12})frac{0.0016}{0.0047}[/tex]

Which is 3.01*10^-12, which is apparently incorrect.

Any uides where I have have gone wrong?
