I made two conductive plates out of aluminum foil wrapped around cardboard pieces
i don't have a micrometer with me to measure to the thickness of my paper, so i just googled the average thickness of paper; also just googled the relative permittivity of paper..$$C=\epsilon_r \frac{A}{d}$$
$$\epsilon_r= 3.85$$
$$A=0.21m x 0.146m$$
$$d=0.103mm=0.000103m$$
$$C=3.85\frac{(0.21)(0.146)}{0.000103}=1146.029F$$
what the heck?...
i must've messed up somewhere! because...
(4nF)
The yellow post-it pad and the cup was just to press the plates closer.
1.) what's with the ridiculously high value i got for the capacitance?
2.) what's with the ridiculous discrepancy?unrelated Q: when posting 2000x2000 images, is there a way to just resize it here??
