So I'm a complete beginner at this. I know ohm's law and generally what components do, but I've never tried to put anything together yet.
I have these 3v motors that don't seem to want to be in a series with anything. They run fine in parallel with each other, but I can't put anything with them. I've tried resistors, other motors, voltmeters, and photoresistors (even when it's right under a light) (The photoresistors work right, I've checked them with my voltmeter). It's bizarre, any little thing and the motors just stop working. I've tried 4v and 6v and it, so there should be plenty of extra current around. So, what gives?
