1. What makes an AC current rating different from a DC current rating? I was taught that AC crating were always given in Root Mean Square (RMS), and that RMS is the DC equivalent.
2. Why are technicians taught electron flow, but engineers are taught conventional?
3. I've seen some schematics here that have diodes with the arrow facing away from an IC output. In electron flow, they teach that current flows in the direction opposite the arrow. Meaning the current is flowing into the IC output.... why would that be desirable? I just learned the term sinking... is that what is happening?
4. How can a device operate on 26VAC OR 26VDC when the supply is the same terminal for both. Or in other words i can plug 26Vac into the same terminal as I can plug 26VDC into. Can a bridge rectifier pass DC without any other modifications? This question is in regard to LED lighting systems.
