Hello.
I've built a constant current source based on an LM324 op amp.
(schematic attached)
I'm trying to turn on and off the LM324 with a transistor (T1).
What I expect is when i cut off power to the base of T1, the output of the LM324 (pin 1) becomes 0V, but the voltage actually goes up.
Please tell me what i'm doing wrong.
