ezidiegwu (se5762) – hw 8 – Opyrchal – (121006) 1 This print-out should have 10 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 (part 1 of 2) 10.0 points The circuit has been connected as shown in the figure for a “long” time. 6 V S 14 μ F 8 Ω 16 Ω 4 Ω 20 Ω What is the magnitude of the electric po- tential across the capacitor? Answer in units of V. 002 (part 2 of 2) 10.0 points If the battery is disconnected, how long does it take for the capacitor to discharge to E t E 0 = 1 e of its initial voltage? Answer in units of μ s. 003 10.0 points In the figure below the battery has an emf of 15 V and an internal resistance of 1 Ω . Assume there is a steady current flowing in the circuit. 8 μ F 11 Ω 3 Ω 1 Ω 15 V Find the charge on the 8 μ F capacitor. Answer in units of μ C. 004 10.0 points Dielectric materials used in the manufacture of capacitors are characterized by conductiv- ities that are small but not zero. Therefore,

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.
