| Subject - Electrical Abbreviations | |
| jproffer62233 |
forgive me if this seems like a silly question (and I'm sure to alot of you, it does), but what do the electrical abbreviations stand for?...not all of them that i may EVER see obviously, but specifically, on the "power wheel" as seen in the images and drawing section..."P", "R", "E", "I"...and any others anyone can think of that are seen alot (I know you could write a book, but maybe just the major ones) . I know how to do alot of electrical work, but without any formal training, I've never seen alot of these abbreviations before and any help would be knowledge greatly appreciated. Thanks in advance.

| JimmyDee | P = Power or watts R = Resistance E = Voltage I = Amperage Jim |
| jproffer62233 | thanks so much Jimmy (again), and thanks to all who may reply at a later time (I wish I could come on and thank everyone that replies to any post I submit as they reply, but thats not possible for obvious reasons) but anyway, thanks to you all.

| cs409 | jproffer,,,,if you live near a home depot, go into their electrical department and pick up a copy of UGLY'S..... Its a 5x7 or so in size, its Yellow in color and may help you with some of the discussions you see on the forum.....under 10bucks... |
| aussiesparky | Jim Why is "E" used for voltage and not "V" ? Is there any specific reason or is just how it evolved? |
| JimmyDee | voltage = electromotive force = E please don't ask about I  Jim |
| David Hyatt | Historically, the symbol for current, I, came from the German word Intensität, which means 'intensity'. |
| JimmyDee | Thanks David I never knew that. Jim |
| Ryan_J | Remember that these values existed long before some of the people who mastered the concepts where even born. We use "E" for voltage (EMF) because Volta wasn't even born when they had to come up with a name for the phenomonon that we now call "Voltage". Same with amperage. Same with "Ohms". |
| cs409 | sorta like before area codes and direct dialing LOL....Jimmy you remember those days LOL i do!.....hope all is having a hot summer like myself.... |
| JimmyDee | quote: 5 digits and operators and party lines and area codes??? (What would you need that for?) Hot summer? It got to 70 yesterday, 76 so far today. Its been great. Jim |
| cs409 | i dont think they used any codes! it was just like running up and down the highways,,,,i can remember hearing the operator in port arthur, contact one in Lake Charles la.(75miles) and tell her to do so and so,,,,,after a few my aunt on the phone in NC said hello!! in the mid 90s with 100hum... |
| SteveMc | CS409, At what temp/humidity do you avoid attics? The temp is about the same here as where you are(mid 90's 100% humidity) and I spent most of the day in an attic....Reminds me of the "box" in Cool Hand Luke |
| JimmyDee | I did them no mater what temp they were. I did refuse to go into them with the blown fiber glass or rockwool. My friend got talked into having 24" of fiber glass blown into his attic and I asked him who he was going to get to go up there. He said he was at least safer than the people that have the ground up newspaper blown. I of course disagreed with him. That newsprint may stick to you but it washes right off. Try that with glass. Jim |
| cs409 | attic work depends,,,,,,,if its something that just has to be done, it gets done.... most attic work this time of year is 7am,,,,,after 12noon, its not fun,,,i do have a blower with duck, but its still not fun....use a mask now days,,,the insulation dust kills me....if its something that can be put off till cooler weather, then that is the best.... |
| veganfan | Isn't E for a power source with continuous supply, and v volts actually just a potential difference which when connected will immediately neutralize its self out? |
| JimmyDee | It is my understanding that V and E are one in the same reguardless of the source, type of source or the steadyness of that source. It is potental difference or could also be called pressure. Jim |
