A rheostat is a resistor with variable resistance.There are many type of rheostat,involved of a rotary-type rheostat and a sliding rheostst.I dunn know much about the rotary-type rheostat but I can tell u how does a sliding rheostat work.
A sliding rheostst consists of a coil resistance wire wound on a tube and a sliding contact.The sliding contact be moved on the metal bar.Consider of the length of the resistance wire which let electric current through increases,the reistance would be higher and decrease the elctric current.Thus by moving the sliding contact,we can adjust the size of electric current.It's ofter used as a dimmer or to adjustl the voluime of the radio.
If you are interested in the rotary-type rheostat,try to find it by yourself!
What else can I help you with?
Can a rheostat be used to control speed on a capacitor run motor?
No. If you attempt to reduce the voltage to a cap start motor by using a rheostat, you can destroy the motor.
What is the rheostat?
It is a variable resistance device which control the flow of current
What is the name used for a high power variable resistor?
Rheostat
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 resistance box and rheostat?
Resistance box will provide resistance of discrete values such as 1, 2, 3 ohms or 0.1,0.2, 0.3 ohms. So interim values are not possible. But rheostat gives a chance to vary the resistance continuously. It may be 5 ohm or even 5.769 ohm. So just to fix current for a specified value such 1.5 ampere resistance box will not be suitable where as a rheostat is the most suitable.
What is role rheostat?

Where does lost energy in a rheostat go?
It is lost in heating the resistive material of the rheostat.
What is the hypothesis of a rheostat?
The hypothesis of a rheostat is that by changing the resistance in a circuit using the rheostat, the current flowing through the circuit can be varied, thus regulating the output of the circuit.

How is a rheostat use as a potential divider?
_____________ J| -_____/\/\/\/\_________+ | | | - + | |___i|i|___| E Well this is the circuit diagram , where r is the sliding jockey of the rheostat and a cell (E) is connected in parallel with the rheostat. By adjusting the jockey resistance of the rheostat can be altered which in turn would regulate the potential offered by the cell E to the main circuit. And thus a rheostat can be used as a potential divider.

How do you connect a ceiling fan to a rheostat?
To connect a ceiling fan to a rheostat, you would need to replace the fan's existing speed control mechanism with the rheostat. This involves wiring the rheostat between the power source and the fan motor. Make sure to follow the manufacturer's instructions and consult an electrician if you are not familiar with electrical work.
