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 anybody 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.
