    If you have forgot or lost your password you can use the Lost Password Recovery Form

    On this form you should enter the registered email address for your user account. An email will be sent to that address shortly after entering the details with instructions for resetting your password.

    Since passwords are encrypted, there is no way to resend the original password; this option provides you with the ability to reset your password.

    You must be able to receive emails to your registered email address for this to work. You may need to check your spam filters and folder if you do not see this email shortly after requesting a password reset.

    If you are experiencing problems, please post in the Feedback and Suggestions Forum which allows Guests to post, where an administrator will deal with the issue. Please note, for security reasons, we will not manually send passwords for accounts to any user provided e-mail address - we will only deal with the address registered to that account.

    We have added a Videos section to the main All About Circuits site as a compliment to the E-book Volumes and Worksheets. The video lectures were created by by Tim Fiegenbaum of North Seattle Community College and are available on a variety of topics, including:

    • Electronic Systems
    • Basic Electronics and Units of Measure
    • Basic Components and Technical Notation
    • Circuits
    • Circuit Troubleshooting
    • Alternating Current
    • Inductors, Capacitors, Transformers
    • Semiconductor Technology
    • Diodes and Diode Circuits
    • Transistors and Transistor Circuits
    • Op Amps and Op Amp Circuits
    • Digital
    • Microprocessors

    Questions and Answers:

    How do I view the video lectures?

    Navigate to the Videos section on the main site. Select a video to watch and the video will automatically load and play. You can stop and pause the lectures at any point, and scan through the lecture using the scroll-bar.

    Note: the video lectures require the Adobe Flash Player plugin to be installed in your browser; if you don't already have it, you can download it from the Adobe website:

    Are the video lectures available for download so I can use them off-line?

    Sadly not. The videos contain a number of copyrighted images and were posted only through permissions from the publisher. For that reason they are available for viewing but not for download.

    Please let us know if you have any issues with this feature.

    Many web browsers these days have spell-checkers built into them, or can use add-ons to add spell-checking capabilities. However, this is not the standard set-up on the majority of web browsers in use (notably Internet Explorer).

    All About Circuits has spell-checking built into the forums and blogs. On the Post Reply screen or the Quick Reply dialog, select the spell-checker from the formatting toolbar:


    This will open the spell-checker from where you can select corrections for misspelt words:


    For each misspelt word you are able to Change or Ignore the words like you would in any word processor. The spell-checker gives the option for Learning words not currently in your dictionary, and also has a Look-up function if you want to check the meaning of a particular word, and a Thesaurus for looking-up alternative words - checks at Merriam-Webster On-line (see, .

    The spell-checker checks the spelling in English(US).

    Previously I blogged about the Socratic Project, a free project of worksheets and questions designed to support the material covered in the AAC e-book.

    Recently the Socratic Project was fully integrated into All About Circuits, available from here. As per the original project the following categories are available:

    1. Basic electricity
    2. DC electric circuits
    3. AC electric circuits
    4. Network analysis techniques
    5. Discrete semiconductor devices and circuits
    6. Analog integrated circuits
    7. Digital circuits
    8. Mathematics for electronics

    We have, however, developed the original concept somewhat. The original Socratic Project was available as downloadable PDF files of the questions and answers. The worksheets section at All About Circuits actually goes one step further, we have implemented a fully interactive system:


    Page Activities - Useful activities for the worksheets including downloadable PDFs of the worksheets a (note: the PDF link is for the worksheet you are currently viewing), print options to enable printing of the worksheet direct from the website, and link and blogging options for a range of services.

    Related Pages on the Site - Gives links to pages that are similar to the current worksheet. These pages may contain information that is relevant for the current worksheet or provide supplementary information.

    Page View History - Provides a history of your recently viewed pages on All About Circuits, including worksheets and e-book chapters.

    The question on the website are fully interactive: under each question there is a Reveal Answer link. Selecting this option opens a frame within the current page:


    The answer to the question is given, including supplementary notes to help the reader understand the concepts analysed in the questions further.

    To remove the answer frame just select Hide Answer.

    This is built on the first version released in August 2008. We are always look at feedback and corrections to the material, so if you see an error or wish to make a suggestion, please post in the Feedback and Suggestions Forum.

    Several people have asked me about downloadable versions of the e-book. All 6 volumes are available for download as PDF files:

    Since the e-book is a continuous piece of work and is constantly being updated, please be aware that these PDFs may not be the most up to date versions. For the latest versions please refer to the on-line e-book.
