  1. im just giving 1.5 as example. i just need to know if power loss is more with lower volt given the same wire and same current. not as percentage of each power. just simply which would heat up faster. thanks all, now i understand this. the first line is the answer i looking for. i just needed more info on it, got it in quora
  2. So power loss rate would be same for say 1000V 5A versus 100V 5A ? This is what my question is. I need to know if i can still run same amps rated for 1100v on a 200v circuit. or if i need to get bigger cable to run same amps at lower volt the original was just asking what "in conduit trunking" is. english is not my native so i didnt knew. plus i added more info on my main question since my intended question was missed because i was too vague. thanks i totaly forgot about sizing up to minimize loss. its for wiring our new house, since the profesionals here in my place are plain dumb. plus electricians dont do the controlled testing to know these things and lack the scientific knowledge. so its a science guy job to figure these kind
  3. really? i always imagine high volt allows for more current before overheat.
  4. [edited: now i know conduit spec meaning] [edited] My question was vague, what i want is, wire specs are tested at 1100v , where for example 1.5sq mm copper is rated at 16amp. But my application is 200v, i would guess that lower volt heats up wire faster. so should i use R=V/I to lower amp for 200v ? or the resistance is independent of the voltage.
  5. Texas Holdem (consisting 6 players) i got AA as starting hand, what are chances of there being another A on one of the 5 cards on table? what are chances of 2 other A on the 5? 1. So my question is, when u have pair as start. What are chances of you getting "3 of a kind" and "four of a kind"? 2. Unlike commonsense, I believe starting hand of 10 J is slightly better than K A, since u can make straights on both sides. Am i right? who can calculate it? please
  6. Ouh I make them with brailles, they the best. Because it helps my dog to exercise by playing catch. Dog would bark and spot it by sound feedback by the raised dots
  7. yes I love the bracelet, how did u guys know. bracelets are my hobby OMG
  8. Well science is ongoing process, so old thoughts about science always are changed or improved upon over hundreds of years, so its very possible it aint the limit like fiveworlds telling. and 5worlds, I don't see why lia needs to rephrase it, as even a 10 year old can read that. if u have mental disability for not being able to make sense of partial info, you are indeed unlucky. any proper human can tell its a human by a circle and 3 lines, without needing to draw all the correct proportions and colours and shadings. nw u must get it. dnt be such hypocrite!
  9. ya i know exothrmic, i stateed tht in reply, Captian Panic u give most scientific/best answer (i post this in 2 other forums, both more active thn this more ans)
  10. i dont understand both, i have also test this with ac and thermomtr and why is 36C hot becoz we release heat???
  11. Why is it the most comfortable temperature 22 to 26*C, and anything above 30C is hot when our body is 36*C
  12. Does aplying oils on rusty metal witout 1st cleaning off the surface rust still prevents furthur rusting as long as the oil is there, or rusting can still continue inside? Is there liquid or something that can wipe off rusts like magic
  13. good ans, that what i tot of too, but jst posting hoping sum1 might share real experice strange thing to ponder on, and my vocabulary jst grew, havnt heard of charlatan before ;]
  14. im 20 and dont believe in stupid Gods from early this year, but this is so strange: well, it was 3 years back i think, Henry Hinn (younger bro of Benny Hinn,the famous preacher,healer) was hving crusade in our city, on football field(not stadium), after his prayer, he proclaim miracle healings, the strange one among those is: on the opp side to the podium he was standing was a 5story building, where people are wacthing from the top 2 veranda, He said (i dont remem exact) pointing towards that veranda, ''The girl with Cancer raise up your hand, your healed'', than 1 girl around 35 (on top floor veranda) raise her hand. WTF is that?
