Unformatted text preview: University of California, Berkeley Spring 2010 EE 42/100 Prof. A. Niknejad Midterm Exam (closed book/notes) Tuesday, February 23, 2010 Guidelines : Closed book. You may use a calculator. Do not unstaple the exam. In order to maximize your score, write clearly and indicate each step of your calculations. We cannot give you partial credit if we do not understand your reasoning. Feel free to use scratch paper. Electron charge q = 1 . 60217646 × 10- 19 C. KCL: Kirchhoff’s Current Law states that the net current flow into a node (or super-node or any closed surface) is zero. summationdisplay I k = 0 KVL: Kirchhoff’s Voltage Law states that the net voltage drop around any loop is zero. summationdisplay V k = 0 Power flow into a component: (positive means power is absorbed or dissipated. P = I · V Ohm’s Law: V = I · R or I = G · V where G = R- 1 . Power dissipated in a resistor: P = I 2 R = V 2 G Resistors in series add: R = R 1 + R 2 + · · · Conductances in parallel add: G = G 1...
