Homework 2: BME 302L, Spring 2010 Due: Tuesday February 16 Preview accepted Tuesday February 9 Exercise 1 (5 points): For the half-wave rectifier on the right, what is the average load current (in mA)? 1. 156 2. 166 3. 225 4. 312 5. 450 115 V rms 10 : 1 22 Exercise 2 (10 points): In the loaded zener regulator on the right, the zener is characterized by V Z = 3.4V @ I ZT = 25 mA, I ZK = 1 mA, Z Z = 12 and I ZM = 60 mA. What is the maximum load current for which the zener maintains regulation (in mA) ? 1. 6.2 2. 14.9 3. 21.4 4. 38.5 5. 59.0 Vz Zz RL 560 12 V Exercise 3 (5 points): From Floyd Textbook, Chapter 2 (pp. 97-104), problem 6 Exercise 4 (10 points): From Floyd Textbook, Chapter 2 (pp. 97-104), problem 8. Use a transformer with a turn ratio of 8:1 and a load resistance of 150 (instead of 4:1 and 1000 ). In addition to the parameters asked in the problem, determine the dc load voltage, dc load current and dc diode current. Exercise 5 (10 points):
