    Please help me calculate wire temperature due current

    The Nichrome wire came up on comment 11 and right away I replied and said that it's sound perfect for what I need :) I prefer not to say what it is about because I may want to write a patent on this. But I tried to be very clear about what I want to achieve, I said that I want the wire to get...

    Please help me calculate wire temperature due current

    Actually I wanted the videos to start at certain timestamp so you will see how hot it gets, but it didn't work.

    Please help me calculate wire temperature due current

    Actually I'm very optimistic now, I found lots of stuff about this Nichrome wire and I think that I can heat it for what I need even with 5V 1A power supply... Here are only few of the things I found:

    Please help me calculate wire temperature due current

    Very interesting, thanks! As I said in my previous post, I think that I will use a Nichrome strand.

    Please help me calculate wire temperature due current

    Thanks very much! I never heard of this, but now I read a little about it and it sounds like a piece of Nichrome thread will be perfect for what I need! The only question is will current of 2A be enough for heating the wire to about 40-60°C ? which I estimate that it's exactly what I need...

    Please help me calculate wire temperature due current

    I will limit the current to 2A (using resistors) in order to prevent damage to the power supply. Giving this, can you tell me what will be the temperature of the thread after 1 minute? Indoor, room temperature of 25°C.

    Please help me calculate wire temperature due current

    So... can you give me a number? Can you say if (after 1 minute) the thread will heat to at least 60°C? I want to know if I have to buy power supply of 12V (DC) 2A, or do I have to buy a 12V, 4A power supply? I don't want to waste too much money on experiments and equipment.

    Please help me calculate wire temperature due current

    I looked at your link, sorry but it's like Chinese for me. Why the info I gave is insufficient? What data is missing to be able to calculate it? I said that it's a 1-2mm thick copper thread, I gave you the current through the wire (2A), what else is missing?

    Please help me calculate wire temperature due current

    Thanks, but I know all that... I thought that using the data that I gave it will be possible to give me the actual temperature... Again: Single thread that pulled out of the speaker cable (like in the picture) I estimate that it's a 1-2mm thick copper, the length of the wire will be about 50...

    Please help me calculate wire temperature due current

    Hi, I need to calculate the temperature of a wire, due electric current passing through, and I have no idea how to do that. I need it for a device that I want assemble. I'm using one single thread (strand) of speaker cable, like you can see in this picture: Again, Just a single thread that...
