4 Symptoms Of A Bad Or Failing Blower Motor Resistor
If the blower motor resistor is bad, your blower motor can get stuck on a single speed. There could also be various airflow settings that won't work or you could fail to get air at all. On top of that, the fan speed can become inconsistent or intermittent, making for an uncomfortable drive. How long does it take to change a blower motor resistor?

What is a Rheostat? Working Principle, Types, Applications
The rheostat is a variable resistor used to control the electric current by increasing or decreasing the resistance manually. It is a large-sized resistor type used in applications that require current adjustment or resistance change. It is placed in series in a circuit. The current controlled by rheostat is greater than other variable resistor ...

Crane Motor Control Resistors
When overhead cranes are used in industrial facilities, crane resistor banks are frequently used for control of hoisting and lowering speeds, as well as positioning the crane itself. Resistors are usually mounted in, or on top of, the bridge structure.Many steel mills use DC motors because, in the past, DC power was the best way to hoist heavy loads.

A Complete Guide to Rheostats
A variable resistor - such as a rheostat or potentiometer - can be easily altered by the user. The basic function of a rheostat in a circuit is to adjust the amount of current flow as and when required. As such, potential rheostat uses in electrical circuitry are many and varied. By far their most common application is as power control devices.
