It's the techs against the engineers, as usual. |

Well, here you've opened up a whole can of worms. First of all, current flow is thought of as realtive by Engineers....for example in a bottle of pop..oops...soda....are the bubbles going up, or the liquid coming down? Actually, it's only the Physics guys who use electron flow when talking about current...and most of them can't figure out how to use the test equipment anyway without a $100K budget. Yes, Engineers and Techs both view current as flowing from the positive source to the negative. Even the schematic for a diode has the arrow pointing in the direction of curent flow. (By the way, the biggest mistake anybody can ever make is confusing a car battery ground with "minus twelve" volts. It just ain't so.) Now, as far as tech's under the hood and engineers in the driver's seat, I can't count the number of times some wise ass-tech has commented "the engineer who designed this obviously never had to work on it". Well, that's true. There are poor engineers as well as poor doctors, lawyers and technicians also. For me, I always figured two heads are better than one, so I work with the technicians, not tell them left from right. And by the way, I always remembered which side port was on due to its having 4 letters, same as "left", also...chuckle. |
