We use the same greek letter to mean 100 different things in various sub disciplines of electrical engineering.Īll that really matter is that you understand what voltage is, what current is, what resistance is.
#TROLLING NOOBS CRITICAL OPS THUMBNAIL FULL#
Engineering is full of weird stuff like that. You can step outside of it, but when discussing issues with other people do you want to spent all your time arguing minutia, or do you want to solve the problem?Ĭlick to expand.I don't think it really matters man. That isn't changing either.Ĭonvention sets the common language and concepts we all use to communicate.
If people hit a certain point in electronics where they need to match the laws of physics to electricity they have to relearn several things, until then it doesn't matter, and conventional current flow is taught as standard. There is quite a bit if physics that says other, but again, it is convention. We still have people argue that electron flow is wrong, and conventional flow is still taught in schools. If everyone gets feed up with convention then things change, but the fact is it currently works. You can use whatever you want, it doesn't matter, but it you are talking to someone else all of a sudden it becomes critical, because like as not, they in turn will talk to other people. That is not going to change.ĭitto as to letters used to describe Ohm's Law. Ground used to mean a long rod into the earth, now it means more. Thing is, no one person defines convention, it is what it is. If I'm wrong correct me so maybe I'll understand better.Ĭlick to expand.We've had the argument before. But I like to call a spade a spade.Īmps is speed. so a big thumbs up from me on changing C to V. Calling volts Current is just plain wrong. You have it 2 thirds fixed by changing volts to V. So can someone please explain to me why I now have to start calling amps intensity? As a concreter I used to win arguments with engineers regularly. just didn't show some of the workings out I may need to do year 11. even though I taught my grandmother to use it, and my uncle (the radio guy) backed me up. Got failed for inventing a new way to do it when I was 13, just because the teacher didn't understnd my method. I could multiply fractions with uncomon lowest denominators since I was 11. I was doing algebra 2 years above my age before I got tired of being held back at school and got a job as a concreter at age 13. sorry.Ģ0 years later I finally have the determination to tackle it again. so you just learnt to deal with it and moved on. it's simple, yet nobody seems to understand. Maybe it's the hundreds of times I have been zapped, including lightning at least once (running through storm, so feet of the ground.) But the theroy has always bugged me. Except I get electricity in a way few people do. (I was lucky enough to have a radio genius as an uncle to explain things to me) is this need to use 400 year old terms, created by people that didn't have half the understanding of electricity I did at age 10. The thing that threw me off ohms law, and all of electronics after that. How many side by side and how fast they are traveling.
It's all describing Coulombs (I forget how many electrons in a coulomb). amps as the speed, and watts as the expression of both factors combined. I always saw volts as the size of the water pipe. No one can explain I or c to me in a way that makes sense. no disagreement from me.īut why different letters to describe the same thing? Amps are amps. I have to admit to not reading the txt or doc's properly yet.
Never understood why the different letters.
Got my first multimeter when I was 7 years old. I've been playing with eletricity for 20 years.
