Hi all...
i am trying to build a small heater using a 1.5mm dia nichrome wire. initially i tried using a small piece of wire around 20mm length and connected to a 12V,2A DC power supply. but instead of wire getting heated up, the DC power supply gets shorted. why this thing happens. do i need to add any circuit to control nichrome wire.

the same i got 0.2mm dia nichrome wire... it works great with 12v power supply. then why do this 1.5mm dia wire creates an issue.
