Unformatted text preview: 10.6v 10k Ω 5k Ω HW4, PHYSICS 127A 2010 1. Compute the voltages and currents for the diode circuit on the right. Most problems are embedded in text of Horowitz and Hill textbook. Additional Exercises are at end of chapter. 2. HH Ad. Ex. Ch. 1, pblm. (7). (Diode limiter). 3. HH 1.29 (Battery Charger) 4. HH 1.27 (Full wave rectifier supply). 5. Solve the currents and voltages for the diode circuit below, which we will use later to understand transistors. Note: The symbol 11.2v refers to a 11.2 volt supply connected with respect to ground (0 volts), which is the bottom symbols with 3 horizontal lines. (Hint: Transform the circuit in the dotted box into its Thevanin equivalent at the right.) 11.2v 10k Ω 5k Ω A B 10k Ω A 5k Ω B 5k Ω 10k Ω 6. (a) Find the output voltage of this zener diode source. From the table in the data sheet attached to the end of this file, find the zener voltage specifications for the 1N5231B part. (b) What is the current flowing through the zener diode? (c) Using Figs. 8 and 10 of the data sheet, estimate the output resistance of the source. (d) Calculate the drop in the output voltage if a 20 k Ω resistor is placed across the output. 10v 500 Ω 1N5231B 20k Ω 1N5221B to 1N5267B Document Number 85588 Rev. 1.6, 22-Dec-05 Vishay Semiconductors www.vishay.com 1 94 9367 Small Signal Zener Diodes...
