I think it is a very simple test to perform, but I do not know the correct equipment for this.
I just have a basic LED circuit, resistor before LED, but I want to test a short in parallel with the whole circuit. I was able to test this with a normal Voltage power source but after sometime it burned. During this test the Voltage went down to almost 0 V, and current went as high as the source was able to supply.
Is there some sort of equipment to test short conditions? I am intending to test current(mA) against temperature.
Any help will be appreciated. Thanks in advance.
