Version 001 – HW08 – gavrin – (25111) 1 This print-out should have 13 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. TransferofElectrons 001 10.0points Two conductors insulated from each other are charged by transferring electrons from one conductor to the other. After 1 . 6988 × 10 14 have been transferred, the potential difference between the conductors is 13 . 2 V. The charge on an electron is - 1 . 60218 × 10 - 19 C . What is the capacitance of the system? Correct answer: 2 . 06195 × 10 - 6 F. ParallelPlateCapacitor07 002(part1of4)10.0points An air-filled capacitor consists of two parallel plates, each with an area of 6 . 11 cm 2 , sepa- rated by a distance of 1 . 82 mm. A(n) 30 V potential difference is applied to these plates. The permittivity of a vacuum is 8 . 85419 × 10 - 12 C 2 / N · m 2 . Find the magnitude of the electric field be- tween the plates. Correct answer: 16483 . 5 V / m. 003(part2of4)10.0points Find the magnitude of the surface charge den- sity.

### What students are saying

• 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.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
