## Main Question or Discussion Point

Hello,

I have made a capacitor with two aluminium foils separated with paper dielectric with,

dielectric constant (K) = 3.8 for paper material

paper thickness, D = 0.1mm = 1e-4 m

plate or foil area, A = (12.1 x 8.3)cm = 0.010043 m

air permitivity, Eo = 8.85e-12 F/m

Calculated capacitance = (K Eo A)/d = 3.3 nano Farad

When I measured the capacitance i got,

Measured capacitance = 125 micro Farad

Can any body explain why this huge error is existing? I have tried with different foil areas but could not find the reason of error.

I m looking forward, Cheers.
