How to i get a spark out of copper or nichrome wire? Which will hold more electricity? If i connect one end of wire to one pole of a battery then connect the other pole of the battery to the wire (not the end of it but apart of the length) will that get a current running through the wire? How can i check if there is a current running through the wire? Thank you!Oh one last question (not related, i am not making explosives!) I heard that non dairy coffee creamer is flammable and flour is as well, well which is more so? also is it only a certain type of flour? i think it really is amazing that people ingest this stuff, thats all.
You ask how to get a spark out of copper or nichrome, and next you ask if common cooking ingredients are flammable, and state you are not interested in explosives? It's kind of hard to believe. All foods are flammable. That's why they are foods. Almost none of them are explosive except as airborne dust, and then only in certain concentrations. Connecting copper, nichrome, or iron wire across battery terminals will result in almost instantaneous melting and some vaporization of the wire. If you do it with bare fingers it results in 3rd degree burns. (They are flammable, as well.)
Nichrome is used primarily because .. 1) it resists high-temperature corrosion (ie oxidation .. reaction with atmospheric oxygen) that will weaken the wire over time, causing it to break or burn out. 2) It has a higher melting point (1400?C) .. (Cu 1083?C) Resistivity considerations are largely irrelevant since the length/thickness of wire is chosen so that it has the resistance (R) required to transfer heat energy at the required rate (power P) .. P = V?/R (W) .. where V = applied voltage (same for both wires)
