resistor is a passive component which opposes the current flowing through a closed ckt.
use in opposition of current in ckt .
Because for each speed except the higgest one, to slow the motor of the fan, a resistor is choose and it's a big resistor, bigger to slow the speed and after long use or if the motor is defect (use to much currant), the resistor burn and no currant can pass trough
It depends on where you are going to use this resistor and what its application going to be. If the circuit you are using can tolerate this then you are fine.
heat not working
You can only use a resistor to drop a voltage at a constant current. If you know the current, use Ohm's law to calculate the resistor value.
its easier to undo the motor and test that if that isn't working then it will more than likely be the resistor
YesYes
I installed a resistor inline with my oil pressure sensor. The resistor in a circuit will usually disperse energy as heat.
yes you can! you can use a multimeter and a resistor.
You need to use the 250 Ohm resistor in series with HART protocol communication because it acts as a shunt resistor.
No, Using a resistor spark plug with resistor wires can create too much resistance for the ignition system.
you need a new blower motor resistor with auto temp control
The blower resistor gets overheated and burns out usually because the blower motor is failing also.
