Question

A National Instruments recruiter is interviewing you for a job. She is a UTEP alumna and is very proud of it. She asks if you took Electromagnetic Field Theory with Dr. Flores. You say "yes Ma am, I did." She then smiles and tells you "surely you've seen this problem. Can you solve it?" Without hesitation, you say oh you betcha, yeah!" Suddenly, you realize that you're a step away from getting a job offer. A capacitor is made with three dielectric slabs as shown below. The voltage across the conducting plat is = 6 V. The structural dimensions are L= 1 cm and d=0.1 mm. The relative permittivities are ei 2,2 4, and 3 8. Determine the following: Oolcm es a) (40 points) Total capacitance of the device. b) (10 points) Amount of energy stored c) (20 points) The electric field E between the plates. d) (30 points) Flux density D in each slab. charse Den s O-01cm d/2 L/2 51 103
