Physics II Question!

SerPSE9 28P045,Wi Determine the capacitance ar Tcnon-fillod parallel-plate capaotor having plste arco of 1.65 cm- and a plate sparation of .030 0 mm Determine the maximum potent el áfference that cen be applied to 5 Teflon-filled perellel plate capacitor hen g plete areo of 1.65 o 2 and plete seperation of 030 0 mm, Need Halp?t An electric dipale consists of charges e andseparated by 0.62m. It is in an electric field of strength 5.10 10 N/C. The (imaginary) ine connecting the two charges forms a 38 angle with the electric field What &the net force on the sloctric dipole? What is the net torque on the clectri dipolc?

Explanation / Answer

here,

6)

the plate area , A = 1.65 cm^2 = 1.65 * 10^-4 m^2

sepration , d = 0.03 mm = 3 * 10^-5 m

dielectric constant of Teflon , K = 2.1

the capacitance , C = K * area * e0/d

C = 2.1 * 1.65 * 10^-4 * 8.85 * 10^-12 /( 3 * 10^-5) F

C = 102.2 * 10^-12 F = 102.2 pF

b)

dielectric strength of Teflon , E = 1500 KV/inch = 59055.12 KV/m

the breakdown potential , V = E * d

V = 59055.12 * 3 * 10^-5 KV

V = 1.77 KV
