I would like to create a food heater , the heater should reach around 80C. I had an idea of using a copper wire (or any other metal / alloy) , connecting it to a power source , and thus heating the wire.
What i want to ask is first of all is it possible and do you think the wire will heat , and how much voltage will i need to heat the wire ? . Second question is can i safely cook food using that wire , and eating that food afterward ?.
