I'm not sure if this is the right section for what i'm asking so i'm sorry if i'm doing it wrong but here goes
If you look at the picture i provided, you'll see an attempt at making a flat heating element. So the story is i need a heating pad capable of at least 130 degrees Celsius and preferably running at 12v dc. I made this which at the connectors has a resistance of 0.5 ohms. Each of the bridges have a resistance of 2 ohms. The copper wire i wrapped at the ends is temporary. At first i ran it without those and only the ends heated up and faster than the other parts could catch up, hence the burnt bit on the silicone pad. Now that i've wrapped the copper wire, the resistance came down so low that when i connect it to the power supply, it detects a short circuit and cuts the power. What do you reckon is the best way to approach this? Do i have to scrap it and build a maze like design? Or if i reduce the number of bridges it'll work?
My power supply is capable of 30 amps but i'm not very confident that i can reach 130 degrees with it. Any help or input is greatly appreciated.
