I was trying to make a foam cutter so I connected a 4 inch long piece of nichrome wire in series with 4 D batteries and the wire got very hot. My batteries became worn out and I replaced them with a 9 volt eveready battery but it didn't heat up. I tried shortening the wire up to just a centimeter but still nothing happened. I was wondering if current is even passing through the wire so i wired an electric motor in series with the nichrome wire and the battery, and the motor was spinning. I also tried using two 9 volt batteries in series and in parallel but still nothing happened. I am really confused.. why can't 9 volts and 18 volts heat up the wire while 6 volts(4 d batteries) can??I connected the two 9 volt batteries in parallel too but why didn't it work?
Yeah, they ought to. That's why they were installed in the bathrooms on airplanes, because people would try to sneak smokes in there. (How anyone thinks they can sneak a nasty *** cigarette is beyond me though.) It's possible that there just wasn't enough smoke in the air for the smoke detector to pick up on it, or the battery was dead/dying.
I say a Revlon caz i used some other brand name (which i cant really remember) and my curls weren't so good as I thought they would turn out:( but when i decided to use a Revlon curling iron my hair curls turned out GREAT! so yeah i say go for Revlon.
