ESE 372/Spring 2009 HW1 (problems are taken from recommended book) Due: February 12 th . 1.1. Ohm’s law relates V, I and R for a resistor. For each of the situations following, find the missing item: (a) R=1k , V=10V (b) V=10V, I=1mA (c) R=10k , I=10mA (d) R=100 , V=10V 1.3. Ohm’s law and the power law for a resistor relate V, I, R and P, making only two variables independent. For each pair identified below, find the other two: (a) R=1k , I=10mA (b) V=10V, I=1mA (c) V=10V, P=1W (d) I=10mA, P=0.1W (e) R=1k , P=1W 1.7. A two-resistor voltage divider employing a 3.3k and 6.8k resistor is connected to a 9V ground-referenced power supply to provide a relatively low voltage. Sketch the circuit. What output voltage (measured to ground) and equivalent output resistance result? 1.15. Through related application of Thevenin’s theorem, find the Thevenin-equivalent of the circuit below between node 4 and ground and hence find the current that flows through a load resistance of 1.5k connected between node 4 and ground. 1.21. Find the complex impedance at 10kHz of the following networks:
