Question

A parallel-plate capacitor has plates of area 2.99 Times 10^-4 m^2. What plate separation is required if the capacitance is to be 1730 pF ? Assume that the space between the plates is filled with air? (Dielectric constant for air is 1.00059) Express your answer using three significant figures. What plate separation is required if the capacitance is to be 1730 pF ? Assume that the space between the plates is filled with paper. (Dielectric constant for paper is 3.7) Express your answer using two significant figures.

Explanation / Answer

Part A )

C = k0 A /d

k = 1.00059

substituting given values we get

d = 1.5311 um

B)

similaril here k = 3.7

substituting values we get

d = 5.662 um
