The 2026 edition of my No Nonsense Technician Class License Study Guide is now available for review. I would love for you to download it, read through it, and comment on it, either here in this post or directly by email.
I’ve improved some of the explanations in the text (at least I think that I’ve improved them). But, please feel free to comment and suggest other topics that might need more explanation.
I have also added some illustrations. I was going to add more illustrations—and I may try to add more before I actually publish it—but illustrations take a lot of time. If there’s a topic that you think really needs an illustration let me know.
Finally, I’m looking for suggestions as to what to put on the cover. The last edition had a cartoon image of a young man holding a satellite antenna. That generated a little controversy about not being inclusive enough. I’m not sure it was all that bad, but I’d love to hear what you think would make a good cover.
Like it. want to finish it but at T5A09 the cycle highlighted is negative to positive and the answer is … between positive and negative. Might confuse a newbie. Maybe explain a cycle can be peak to peak and others.
Hmmmm. Thanks for your comment. I’ll take a look at that.
Hi Dan,
First of all, thank you for making your guide available to all.
Ken makes an interesting point. The graph in fig 2 is quite complicated. It shows voltage changing with time. Where is any mention of direction?
As you explain clearly, the voltage increases from zero to a maximum value, Vpeak, and then decreases to zero when it becomes negative, meaning that the current has changed direction. It increases to a maximum negative value, -Vpeak, before returning to zero.
What do we mean by a cycle? I like to think of the current oscillating backwards and forwards. One cycle is one complete oscillation. The frequency is the number of oscillations per second.
