Thats not accurate. Resistors limit current, the voltage drop of the resistor is a byproduct of the power dissipated by the resistor. P = (I^2)R. You CAN use a resistor to control the current to the motor if you know the motors impedance, but most motors are designed to operate at a certain voltage/RPM, and running them at a lower voltage/RPM may limit the airflow through the motor which can generate heat buildup and burn up the motor, which has nothing to do with the resistor.
@programaster No when you use a resistor the voltage is changed to current. A motor cannot handle a large amount of current and will cause the wires to overheat and cause damage to the motor.
@LegendaryTechnology Voltage changed to current???? Wow! Sorry but that is not correct. Ofcourse you can control the speed of a motor with a resistor, but it would not be very practical coz you'd be wasting a lot of energy and need a pretty hefty resistor to dissipate that energy.
the PWM gives adjustable duty cycle but does not reduce output voltage to the motor

Do i absolutely need a resistor between my POWER ( 9V battery) and my Potentiometer ?

This is an old video. I am now aware that much of what I said is incorrect. It's more of a concept video than a how-to video. Thanks for watching!

i don't know his FULLY...I'm a mechanical engineering student...not ECE...so can you give me one reason on HOW ECE DEFEATS MECHANICAL>?

Isn't that a brushless motor

So what? you can't use a resistor to just stop it from burning out?

@LegendaryTechnology I see... So can they handle a higher voltage with less current?
programaster 1 year ago
@programaster Yes, at least to a certain extent.

Your resistor may burn out, but not your motor
