Say I was run a homemade motor using a 9v battery, and then ran it again using two 9v batteries... would it go faster with the 18v??

The strength of the current passing through a DC motor directly affects its speed. This is because the current creates a magnetic field that interacts with the permanent magnets on the motor's rotor, causing it to rotate. The greater the current, the stronger the magnetic field and the faster the rotor will rotate, resulting in a higher speed for the motor.
Yes, the direction of the current also plays a role in the speed of a DC motor. This is because the direction of the current determines the direction of the magnetic field created, which in turn determines the direction of the force on the rotor. In a DC motor, the direction of the current must be constantly reversed to keep the rotor rotating in the same direction.
No, a DC motor is designed to run on direct current (DC) only. This is because AC current constantly reverses its direction, causing the motor's direction to constantly change, resulting in inefficient and unstable operation. However, AC can be converted to DC using a rectifier to power a DC motor.
The number of coils on a DC motor's stator (the stationary part) affects its speed. This is because the more coils there are, the stronger the magnetic field produced, resulting in a higher speed. Therefore, increasing the number of coils on the stator can increase the speed of a DC motor.
Yes, there is a limit to how much current a DC motor can handle. This is determined by the motor's design and its components, such as the size and material of the coils and the strength of the magnets. Exceeding this limit can cause damage to the motor or even result in it burning out.
