### What is a resistor that can be adjusted between minimum and maximum by turning a dial is called a what?

It is a variable resistor. Basically, the same as when you turn up or down the heat on an electrical oven or radio.

### What is the difference between resistance box rheostat and resistor?

A resistance box is a device that contains a set of fixed resistors that can be connected in various combinations to achieve different resistance values. A rheostat is a variable resistor that can be adjusted to change the resistance in a circuit. A resistor is a general term for a component that resists the flow of electrical current in a circuit and comes in fixed resistance values.

### What is the difference between a fixed resistor and a variable resistor?

its the colour of the fixed and the variable we define it by its power and name

### What is the difference between a variac and a rheostat?

A variac is a variable transformer that changes voltage levels, while a rheostat is a variable resistor that changes resistance levels. Both can be used to adjust voltage or current in a circuit, but they operate in different ways.

### Difference between variable and fixed resistor?

Variable resistors means that a resistor which can change its resistance by control by any person or it self and fixed resistor means that it can not change its value.

### When to use a rheostat?

Depending on the situation. The purpose of the rheostat is use to change the resistance of the circuit. The rheostat is use to define Ohm Laws the 2nd situation is use to find out what the fixed resistor's resistance. 3rd purpose : used to control the resistance of circuit. eg Radio

### What is the difference between normal resistance and potentiometer?

Resistors are either fixed value, or variable. A variable resistor has three terminals; one at either end and one attached to a moving 'wiper', and can be connected either as a potentiometer or as a rheostat. So 'potentiometers' and a 'rheostats' are different applications for variable resistors. A potentiometer uses all three terminals, and is used to control levels of potential; whereas a rheostat uses just two of the three terminals, and is used to control current.

### How can a potentiometer be a rheostat?

A potentiometer can be used as a rheostat by connecting only two of the three terminals, usually the outer two, and using the third terminal as the wiper. This configuration allows the potentiometer to act as a variable resistor, adjusting the resistance in a circuit to control current flow or voltage levels.

### The difference between fixed and variable inputs?

### How do you you control the speed of a dc motor?

A Potentiometer, an adjustable resistor, is connected between the power source and the motor. An AC motor would use a Rheostat .

### What the difference between a variable and control?

The difference between a controlled variable and a variable is in their state. A controlled variable is something which is rigid and constant while a variable is liable to change and inconsistent.

### What is difference between thick and thin film resistor?

Difference between thick and thin film resistor is not related to thickness but its based on how the film is applied to the surface.
