Unformatted text preview: Name:()vda (1 One 8.5xll formula page allowed. Otherwise, closed book, closed notes, no calculators. Work each problem in the area provided. You may use the back of the test sheets for scratch area, but they will not be graded. Show your work neatly. Point values for each problem are given. Put your name on each page. There are 6 short problems on this exam. None of them should take more than four or five lines of work to solve. So if you start down a path that is going to fill a page STOPAND THINK. You're making it too hard. Problem 1 (20 pts). Write the meshcurrent equation for the central mesh(A) below, assuming there are other meshes as labeled. If no mesh current is shown in an area, assume that this is the edge of the circuit  there are no additional meshes beyond those shown. Your equation should be ready to be solved for the mesh currents (assumingyou did the same for all the other meshes). R 11 R 1 R 10 +: . > t' '1 t R 9 Name J'Yc{C l (1 10/17/08 Problem 2 (15 pts). You need to first characterize, then predict the output of an unknown "black box" linear circuit that takes a current i 1 and voltage v 1 as inputs, as shown. Sincewe're not testing over chapter 6, there must be no capacitors or inductors in the box! There also appear to be no power supply leads into the box (it's a passivecircuit).power supply leads into the box (it's a passivecircuit)....
