Polarized: It’s Not Just for Sunglasses

Polarization often reminds people of sunglasses, but it’s actually an electrical term as well! Who knew? (Well, I did, but I’m the exception, not the rule). My knowledge of polarization was particularly useful the other day. I was playing a casual game of croquet with my friend, Quincy Quail, when he started complaining about plugs to me, of all things.

“What’s the point,” he asked, “of having those 2 little prong things different sizes? I always try to plug lamps and things like that in, and I end up doing it backward! It’s so frustrating!”

American Wire Gauge vs. International Wire Size

If you grew up in Am1 CONDUCTOR_GREEN_YELLOWerica, meters and millimeters are basically a foreign language.  When I used to read a ruler growing up, I didn’t bother using the centimeter side. Actually, I didn’t even know why it was there. Thinking about it, the one on my desk now doesn’t even have centimeters (I should probably fix that). However, if you grew up on the other side of the pond (or anywhere else for that matter), the metric system is alive and well.

Well with International and North American wire size, it can be just as confusing. For North America, I never understood why as the wire got larger, the number got smaller. Why is 18 AWG smaller than a 10 AWG? Well, back in the day the gauge was determined by how many times the wire had to pass through the drawing dies. The smaller wire, such as 18 AWG, is going to have to pass through more times than the 10 AWG. Actually, makes sense, right? Continue reading American Wire Gauge vs. International Wire Size
