I need to heat up a part of a circuit up to 300°C with ideally a 1.5V alkaline battery and I honestly have very little idea of how this stuff works. I was wondering if a short circuit constructed from a copper wire (60cm in length), tungsten wire (~0.5cm in length) and a 1.5V alkaline battery would work. The length of the wires comes from physical restraints. Will this just burn the battery before it even reaches the desired temperature? Is there possibly a way better solution to solving such a problem (300°C, 1.5V battery)?
In: 4
Let’s think about power: (mwahahaha)
In most wires as temp rises, so does resistance -> for given voltage over time less current will flow
This power will dissipate as heat and then be transferred away from the wire, the hotter, the faster the transfer -> system will find equilibrium based on material properties of the wire (electricity and heat transfer wise) and the geometry (also voltage of course)
You could get these properties and formulae from a datasheet (might wanna search nichrome wire)
[https://www.jacobs-online.biz/calculators.htm](https://www.jacobs-online.biz/calculators.htm) I found this calc on a site that sells those wires, this might already be your answer.
Oh and also, wire that is meant for that stuff will NOT burn up at this temp, 300°C is relatively tame
