Hi, all.
i want to make a small heater. so i bought 0.1mm x 5mm nichrome strip whos resistance is 2.2ohms per 12 inch.
The length i am using for making the heater is also 12 inch. But when i connect this nichrome wire directly to 12V 5amps SMPS, the SMPS gets shorted.
so i connected 4.6 ohms resistor in series with nichrome strip, but still the nichrome strip does not get hot.
