Question

Order the capacitors by their capacitances, from highest to lowest. The dielectric constant for each material is listed in the second table. Material Highest 1.00 Air Paper Glass Diamond Porcelain Gallium Arsenide (GaAs) Germanium (Ge) Indium Antimonide (InSb) 3.50 4.50 5.50 7.00 13.2 16.0 17.7 Lowest Answer Bank C Cз C2

Answer 1

m Gireni y = 14,3 103 8 = 13.9x10²m 4.75 x 106m da = 48.6 x 106m 83 = 8.32x10²m €o=8.85x1012 dz. = 15.6x106m K, = 10 k3= 17.7. using formula of capacitor in the presence of dielectric 5.50 C,= K, to ar, 2 di values from above Putting we get lý 9 85 x 12 x 1 ( 14 33 163 4.756106 C 1.197 NF inf nano farad} Now, Ca = K₂ to ar dr valves from above we get Putting 2 13.6. 12 5.50 *8.8 5x10 хXX 10x10 333 476x106 C2 = 0.680 nF SZ1088HF

Now, Kz to Tr? dz valises from above, we get Purting 17.7% 8.85x1612xăx (8-32x103) 15.68 186 C₂ = 2.184 na C₂ > Cp > Highest С CT G C2 lowest
