It's called a 'variable resistor'. However, it can function as a 'rheostat' (to control current) when two terminals are connected, or as a 'potentiometer' (to control voltage) when three terminals are connected. The terms, 'rheostat' and 'potentiometer' do not describe the device itself, but how it is being used.

What are 3 function examples of resistor?
A resistor is really anything that uses electricity along an electric circuit, for example a light bulb, a computer, a radio, etc.
What is the current in circuit with 6 v battery and 2 resistor?

What are the functions of rheostat?
Rheostat is simply a variable resistor. i.e., typically 3 contacts, either end of resistive element and slider contact that moves along resistive element. So, in old radios would typically be used as a volume control.AnswerA variable resistor may be used to control current, in which case it is called a rheostat. Or it may be used to control voltage, in which case it is called a potentiometer. In other words, the terms 'rheostat' and 'potentiometer' do not describe devices but, rather, they describe two applications of a variable resistor.As a rheostat, the variable resistor is connected in series with a load, and two of its three terminals are used -one of the fixed terminal and the slider terminal.As a potentiometer, the variable resistor is connected in parallel with a load, and each of its terminals are used. The two fixed terminals are connected across the supply, and one of the fixed terminals, together with the slider terminal, is connected across the load.

What do the first 3 bands on a resistor indicate?
The first 3 band on a resistor indicate the value of that resistor.
Decade resistor box?
A variable range of resistors built inside a box that can be varied as per our convenient. For example a set of kilo ohm resistors will be there,if u want 3 kilo ohm resistor then using the knob u can change the resistor value to your desired value. similarly there will be another set of resistors in mega ohm etc
Is it common to use a 4160 V 3 Phase motor with a variable speed drive?
No, a 4160 volt motor with a high inertia load will use a resistor bank in the starting of the motor.
What would cause the fan in a 2000 Nissan Xterra to not work for the first 3 settings?
Good Day The fan has a resistor mounted in the heater box. This resistor is mounted near the fan in the airflow to keep it cool. When the resistor stops working the fan only works on high speed. So you need to locate the resitor, it is held into the unit by two screws and it will have about three wires connected to it with flat terminals. The resistor looks like a pieco of wire coil between the two terminals hope this is of help It's called a BLOWER RESISTOR, and it's mounted under the dash on the passenger side, look underneath the dash on the passenger side it's a little white box with wires it has 2 screws in it buy a new blower resistor unscrew the old one and put the new one in plug the wires in, screw it back in and your done....
What is a trimmer resistor?
A trimmer resistor usually called a trim pot is a small variable resistor it is used in circuits to do preset it is trimmed with a trimmer screwdriver it is made up with a round fiber disc with a layer of carbon with a wiper that run on the carbon layer to change the resistance it always have 3 connecting pins where the center one is connected to the wiper and the other two to opposite ends of the carbon strip.
What is the resistance of a 10-ohm resistor and a 7- ohm resistor in a series?

How can you tell if the switch that you have is a 3 way or not?
You can tell if a switch is a 3-way switch by looking at how many terminals it has. A 3-way switch will have three terminals, including a common terminal and two traveler terminals. It is designed to control a light fixture from two separate locations.
What is a variable times a variable?
It can be a new variable eg x*y = xy. Or it can be a constant eg x is a variable then 3/x is another variable. x*(3/x) = 3, which is a constant.
How many terminals does a two way lighting switch have?
A two-way lighting switch typically has 4 terminals: two terminals for the switched circuit and two terminals for the incoming power supply.
How many terminals in MOSFET?
3 or 4
