I'm trying to wire up a DC motor to a 9-volt battery with a resistor in between, and the motor just won't turn. It works if I connect the motor directly to the battery, but not with the resistor in between. Why is this?
- Motor: 1.5-volt DC motor.*
- Resistor: 270 ohm. (Red-Violet-Brown-Gold) (Because it's what I had laying around)
- Battery: Normal 9-volt battery.
* I'll try to find more specific details, like a datasheet, when I get home. Unfortunately, I don't have the motor with me while I'm typing this question.
More specifically, I am trying to create something like this circuit:
With the intention of, when the switched is flipped, the motor changes direction. However, when I make this circuit, the motor doesn't spin, so in troubleshooting, I reduced it down to a single resistor, the motor, and the battery, with no switch or direction-changing, but the motor still doesn't spin.
