im trying to power a 6v motor with a 9v battery what resistor do i need?
and can you also tell me the equation?
A 9v isn't what you need. If you did use one you'd need to use a BIG 9v, like a lantern battery. I think you'd need a voltage regulator, not a resisitor.
A better way to go with with AA batteries.
ok i will use a voltage regulator
