Thanks Bill, For adding a link to the electrical quizzes on the Forums page. <----- To your left, under the Chat room box. I remember back in the early 2000's when I originally came across ECN, I used to do these quizzes quite regularly. Now, due to my general lack of experience in how things are done in the US, I used to get very low marks in these quizzes. Some would argue that I STILL don't know anything about the US systems.
But, there they are, have a go at them, it's a nice bit of fun and (like me)you might even learn a thing or two.
