Checkout the Socratic Instrumentation Project.
If you are interested in industrial instrumentation, Checkout the book "Lessons in Industrial Instrumentation" at the Socratic Instrumentation project. The project provides work sheets too. You will also find links to public-domain textbooks on subjects related to industrial instrumentation.
Checkout the Socratic Electronics Project.
We are sometimes asked for homework questions. While the Socratic Electronics Project does not provide questions keyed to specific chapters, it does provide questions related to various electrical/electronic topics in the form of "work sheets". The basic concept is to encourage active as opposed to passive learning.

Edition numbers reflect major structural changes to a book volume such as the addition of new chapters, the substantial expansion of existing chapters, or a change in markup language (source code formatting). I may also increment the edition number of a volume due to the accumulation of many smaller changes. For a volume under active revision, one edition per year is normal.
"Last revised" dates reflect non-trivial changes only. Minor changes I make such as typographical error correction and stylistic changes to the text do not warrant increments to this date. New topics added to the text, as well as any outside contributions, are the minimum change level warranting a new revision date. The "Minor revision" date reflects minor error corrections: typographical, spelling, minor changes not involving addition of new content. See changelog for details. Please submit errors, typos, or suggestions to All About Circuits > Forums > AllAboutCircuits.com - Feedback and Suggestions allaboutcircuits-feedback, Feedback and Suggestions forum. Like to see an example of an error submission to allaboutcircuits.com? Otherwise, see Contacts section for address to submit corrections.

Note to instructors:
My commitment to those using these texts as student resources in instructional curricula is to never delete subject matter content as the books evolve through succeeding revisions and editions. New subjects will be added, and existing subjects expanded in coverage, but I will never omit "old" subjects. My experience is that even "obsolete" subjects in electronics hold important lessons for students, and sometimes serve to catalyze creativity in new design work. Unlike publishers, who must consider the page count (printing costs) of a book, my publication costs are zero. Instructors may pattern their lesson plans around the subjects contained in this book series without being forced to change their plans as the series matures.
January 18, 2010 Volume 6 Experiments: Ch 8 555 Timer Circuits, new Chapter 8 completed thanks to Bill Marsden.
April 05, 2009 Volume 3 Semiconductors: Ch 4 Bipolar junction transistors, completed, Ch 7 Thyristors, completed.
November 01, 1007 Thank-you to David Zitzelsberger, who bears the distinction of being the second contributor to submit an entire chapter! Go to Combinational Logic Functions in Volume IV to see his considerable work. This brings the Digital volume IV nearly to completion.
July 2, 2007, Volume 3, Semiconductors, incomplete chapters and sections are being completed over the next year or two. Chapter 1 is proofread and has a new "Attenuator" section. Chapter 2 and 3 have been completed, but need proofreading. Please submit errors and corrections to the forum thread at Ch 2. Warren Young has written "Input to output phase shift" for chapter 8, Operational amplifiers. Read all about it. Expect Chapter 4, "Bipolar junction transistors" in a few months. See changelog. for short new text additions to Volume 2, AC. (D Crunkilton)
June 15 2006; Volume 2, AC has been reformatted to look more like a printed book. The PDF version has floating captioned figures. Not much change in the appearance of the HTML version. No plans to reformat the other volumes due to the labor involved-- unless there is a lot of interest in printing them. My best guess is that the most interest will be in viewing the HTML and PDF's not printing. Some new content in the new AC motors chapter. March 6;The pdf version of volumes are now more navigable with hyperlinks- bookmarks. January 1; -- All volumes have a mini table of contents at chapter head, see changelog. Volume 2 has a new AC motors chapter. (D. Crunkilton)
June 21, 2005; revised October 30 -- All volumes have at least minor corrections, see changelog. Volume 3 has a new Shift Registers Chapter. Spice plots have been replaced by Spice-nutmeg graphic plots, improving the appearance of volumes 2, and 3.
July 2004 -- IMPORTANT -- PLEASE READ THIS! It has come to my attention that I can no longer continue my role as project coordinator and primary author for this textbook series. My life has simply become too busy, and I lack the free time necessary to do a good job administrating this project. See goodnews and badnews for more details. Fortunately, the open-source nature of this project has led others to develop it in different directions, where it will continue to live. The best example of this to date is AllAboutCircuits.com. Please pay them a visit to see what neat things are being done with the books.
A huge thank-you to Dennis Crunkilton, who bears the distinction of being the first contributor to submit an entire chapter! Go to Karnaugh Mapping in Volume IV to see his fine work.
At a reader's suggestion, I made a changelog for all the books. This is a very good idea and I should have done it long ago! In this changelog, you will find a complete listing of all the changes made, and when.
All volumes! HTML code plus graphic images in JPEG format -- about 36 megabytes in size, in .tar.gz format
Click on an individual volume above. A link near the bottom of the volume table of contents page is provided for downloading the PDF version, viewable or printable -- a few megabytes each. Adobe Acrobat viewer can access the bookmarks in the table of contents and index. Otherwise, the open source Xpdf viewer works well, sans bookmarks.
All volumes! One file (liecsrc.tar) containing *src.tar.gz files for each volume. Each of these gzipped .tar archives contains all the makefiles, conversion scripts, SubML text source, image libraries, and graphic images (all formats) needed to compile each volume. About 100 megabytes in its entirety.
All volumes! One file (liectiny.tar) containing *tiny.tar.gz files for each volume. The difference between this source code package and the one shown above is that this package contains only one format type for each image (EPS for schematics and illustrations, JPG for photographs), instead of both formats (EPS and JPG) for all images. This archive is much smaller (because the omitted EPS photographic image files are huge!), but requires that you do a lot of image file conversion to produce either HTML or PostScript/PDF output. About 8 megabytes in its entirety.
GNU/Linux operating system: (what else?)
Vim text editor:
Xcircuit drafting program for illustrations, tables, charts, and equations:
Gimp graphics manipulation program (a Photoshop clone):
Miscellaneous UNIX utilities, obtainable from the Free Software Foundation:
You can download an Microsoft Windows executable of the sed utility, necessary for processing source files for the type of markup language used in this book project, here.
Spice version 2G6, a public-domain program used to simulate analog circuits. Download a statically-linked executable for Linux systems here (spice), or the following three files for execution on MS-DOS systems: spice.exe, 32rtm.exe, and dpmi32vm.ovl (keep these three files in the same directory).
