Capacitors Chapter 26 November 22, 2006 Name Date Directions: Put down all diagrams, equations used in the problem, and all of your work. Follow the steps to problem solving! 1) The excess charge on each conductor of a parallel plate capacitor is 53 μ C. What is the potential difference between the conductors if the capacitance of the system is 4.0 x 10 -3 μ F? Answer F {13 kV} ( Physics for Scientists and Engineers by Serway, 4th Edition, Ch 26# 1) 2) A parallel-plate capacitor has a capacitance of 19 μ F. What charge on each plate will produce a potential difference of 36 V between the plates of the capacitor? Answer F {680 m C} ( Physics for Scientists and Engineers by Serway, 4th Edition, Ch 26# 5) 3) A parallel-plate capacitor has a plate area of 12.0 cm 2 and a capacitance of 7.00 pF. What is the plate separation? Answer F {1.52 mm} ( Physics for Scientists and Engineers by Serway, 4th Edition, Ch 26# 11) 4) An isolated charged conducting sphere of radius 12.0 cm creates an electric field of 49.0 kN/C at a distance of 21.0 cm from its center. a) What is its surface charge density? {1.33 μC/m 2 } Answer F {1.33 μC/m 2 } b) What is its capacitance? Answer F {13.3 pF} ( Physics for Scientists and Engineers by Serway, 4th Edition, Ch 26# 7) 5) The plates of a parallel-plate capacitor are separated by 0.20 mm. If the space between the plates is air, what plate area is required to provide a capacitance of 9.0pF Answer F {2.03 x 10 -4 m 2 } ( Physics for Scientists and Engineers by Serway, 4th Edition, Ch 26# 12) 6) A capacitor is constructed of interlocking plates as shown. (A cross-sectional view). The separation between adjacent plates is 0.80 mm, and the effective area of overlap of adjacent plates is 7.0 cm 2 . Ignoring side effects, calculate the capacitance of the unit. Answer F {62 pF} ( Physics for Scientists and Engineers by Serway, 4th Edition, Ch 26# 18) 7) An air filled cylindrical capacitor has a capacitance of 10.0 pF and is 6.0 cm in length. If the radius of the outside conductor is 1.5 cm, what is the required radius of the inner conductor? Answer F {.011 m} ( Physics for Scientists and Engineers by Serway, 4th Edition, Ch 26# 20) 8) Two capacitors, C 1 = 2.00 μ F and C 2 = 16.0 μ F are connected in parallel. a) What is the equivalent capacitance of the combination? Answer F {18.0 μ F} b) Calculate the equivalent capacitance of the two capacitors in part (a) if they are connected in series.

    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.
