i want to test lm324 in this way:
im using 1/4 op-amps. short circuit all other inputs(5,6,9,10,12,13) to the ground. connect 17 volt,.02 ampere to pin 4, 1k resistor to pin3 and 10 k resistor to pin2(with a same voltage sours 17 volt) and noe LED with a 1k resistor to pin one but LED doesnt lights on?why? i dont know.
