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.
What else can I help you with?
What is the voltage divider theorem?
it is aa linear circuit that produces the output voltage from the fraction of its input. It is also known as potential divider.
Can you use a rheostat on ac motor?
Yes you can use a rheostat to control the speed of an ac motor as long as it is correctly sized (power). A better way would be to use a triac control.
Explain the rheostat and its advantages in electric circuits?
Advantages in electric circuits : Advantages of using the rheostat in electric circuits is optional as you could just use the dial on the power-supply to vary the voltage (p.d.), and therefore the current. The advantage of using the rheostat is that you can control it to give you nice even numbers for the voltage.
What is the advantages of variable resistor?
When we want to regulate somthing ;we use variable resistors for example :volume control in radios and volume in headset. Also , the variable resistors can forms a potential devider in which the overall resistance between the two end points remain the same,but the ratio of the two resistors in the legs changes.so the variable resistor is affectively a potential divider. Also, the variable resistor can forms a potential divider in which the overall resistance between the two end points remains the same, but the ratio of the two resistors in the legs changes. So, the variable resistor is effectively a potential divider.
What are advantages of voltage divider bias over the other types of biasing ci?
You can use more than one type of voltage divider in it. It can sometimes get mixed signals with all the things going on.

What is the difference between voltage divider and potential divider?
its the same
How does a voltage divider work?
The essential circuit of a voltage divider, also called a potential divider, is:
What is the operation of potential divider bias?
Thevenization of the divider circuit will help you see how it operates.
How do you reduce12 volts to 6 volts?
use a potential divider with R2 and R1 being 100 ohms
What is other name for variable ressitance?
Another name for variable resistance is potentiometer. It is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.
What is the voltage divider theorem?
it is aa linear circuit that produces the output voltage from the fraction of its input. It is also known as potential divider.
What is a voltage divider circuit?
The voltage divider circuit is a network of two or more components in series, often resistors, between a potential difference. The voltage between the components will be somewhere between the potential difference across the whole network and so divides the total voltage into one or more intermediate voltages.
Why placing the ammeter between the potential divider and the voltmeter will give an incorrect value?
beacause ammeter is use to measure the current not to measure the voltage
Can you use a rheostat on fluorescent lights?
No, rheostats are not typically used with fluorescent lights. Fluorescent lights require a specific type of ballast to control the current and voltage, which is different from the functionality of a rheostat. Using a rheostat with fluorescent lights can lead to inefficient operation and potential damage to the lights.
Can you use a rheostat on ac motor?
Yes you can use a rheostat to control the speed of an ac motor as long as it is correctly sized (power). A better way would be to use a triac control.
What is the use of net in the volleyball?
obstacle and divider
