I would like to ask how to choose the voltage and current of the heating wire. I have a heating wire with a diameter of 1mm. The resistance of one meter is 1.388 ohms. I plan to use only 10cm length. How much voltage and current should be used to make it work red, not burnt. Broken? There is also a 0.7mm ohm resistance of 0.7mm ohm, a heating wire of 1.4084 ohm and a resistance of 0.7084 ohms. How much voltage and current do you need? Do I have a 12v10a power supply? Which type of heating wire can be used normally?
What is your important parameter? What is the use? Be clear. It’s hard to say. There is only one trick. Using a multimeter and experiment
