Does anyone know of a product that will heat up by using mAmps.

I don't get it

 

I think he wants to make a heater, all electrical items use amps of some level, you just need a piece of metal that won't break if you pass lots of electricity though it, I guess, and then pass high doses of either watts, volts, or amps, depending on which one makes the heat.

 

Thin wire heats up nicely due to its high resistance - just be careful or you'll have something that resembles very hot spaghetti on your hands. If you're actually trying to make a proper heater, it'd be better to use something slightly thicker.

 

1)Welcome to the boards
2)Wrong forum - there's one called "Electronics".
3)What Voltage? 10,000V or 10V?

 

Any resistance. Torch bulbs work quite well, they get nearly white-hot.

But by the Power Law, Heat produced in Watts = Current² x Resistance, so you need a lot of milliamps or a lot of resistance to take the chill off your room.

Explain more.

 

you need to be more elaborate. what are you using it for? are you shrinking heatshrink or are you heating your house? the product depends on the application.
