How is this simple transistor circuit suppose to work? [closed]
I verified that the transistor worked as expected with a voltmeter. … Here is the transistor I used:
As I understand this, the transistor is stimulated to "steal" electrons away from the motors circuit. But it seems connected to the base. Why would you do that? …
