The main power producers in an electrical system are the battery and alternator. The alternator puts 14 volts of alternating current into the electrical system and resistors. The resistors only allow a fraction of the AC voltage produced to reach the systems' sensitive components
Power dissipated = I2 RI = sqrt( P/R ) = sqrt(5/4,700) = 32.6 mA . (rounded)Note:It's only "safe" if the power actually dissipates, i.e. doesn't just hang around the resistor.32.6 mA is 'safe' if the resistor is heat-sinked, or at least out in the open air. It's not safeif the resistor is wrapped in a cozy blanket.
A cement resistor is typically used as a power resistor (a resistor whose power rating is greater than 1 W).
The first 3 band on a resistor indicate the value of that resistor.
A voltmeter can be connected in parallel with a resistor to show the voltage across the resistor.
A series dropping resistor is a resistor that limits the amount of current flow in a circuit.
heat not working
its easier to undo the motor and test that if that isn't working then it will more than likely be the resistor
resistor is a passive component which opposes the current flowing through a closed ckt. use in opposition of current in ckt .
YesYes
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.
Chack the speed control switch and the resistor that controls the speed of the motor
Bad resistor ? Bad switch?
Bad blower resistor?
the blower fan resistor has gone bad.
how do you chage the fan resistor in a 2002 jeep liberty?
your blower resistor is going bad
