Electronics Fundamentals: Understanding Capacitors

[Michael Graves]

Capacitors? A TV repair neighbor (old-time CRT/tube TV) once told me, "Its not dangerous if you keep one hand in your back pocket."

Yep. And my uncle, also an old-time CRT/Tube TV repairman ended up in the next room, flat on his back, because he believed that. We were all amazed that he just walked it off.

CRT voltage is usually very high. We had several sailors killed every year working on systems with them, when I was in the Navy. One of my systems had a difference of potential in the power supplies of 5000 Volts. Just sitting there, on little test pins. You had to know what you were doing, and we were VERY well training in the Navy. There was not a "keep one hand in the pocket" rule, but there were rules about standing on rubber mats, using shorting straps, wearing 10,000V gloves on certain systems, and more. But anyway, capacitors are cool.

Learned electronics in the Navy. Hard ass Master Chief instructor. Version 2 of the resistor color code chant was "bad boys rape our young girls but violet gives willingly" My buddy had a capacitor blow up and the metal top hit him directly in the eye. Back then, not all the tops were scored so it could open, not launch.

That's the second I was talking about however I learned it in the USAF.
