Rheostat 10 Inches
Product Code : SCL-EAE-11281
Quick answer: The Rheostat 10 Inches is a sliding-contact variable resistor of nominal 10-inch size. Moving the slider changes the active length of resistance wire, so the unit controls current in series circuits or provides a variable voltage as a potential divider in school and college practicals. Lab Exports manufactures it in Delhi for schools, colleges and universities.

Two ways to connect the rheostat
As a variable resistor, the rheostat goes in series with the load. One end terminal and the slider are used, so moving the slider adds or removes resistance wire and the current falls or rises accordingly.
As a potential divider, the whole winding is connected across the supply and the output is taken between one end and the slider. The output voltage then varies from nearly zero up to the supply voltage as the slider travels, which is useful when a component must be tested from zero volts upwards, as in lamp or diode characteristic studies.
- Place the rheostat on a dry, stable, non-conductive bench.
- Inspect the resistance element, slider and terminals for damage before wiring.
- Choose the variable-resistor or potential-divider connection and wire it with the supply switched off.
- Set the slider for maximum resistance, or minimum output voltage, then switch on and adjust gradually.

Frequently asked questions
What is the difference between using a rheostat as a variable resistor and as a potential divider?
As a variable resistor it sits in series and changes the current. As a potential divider its full winding is across the supply and the slider taps off a voltage that can be varied from near zero upwards.
Which experiments use the 10-inch rheostat?
Ohm's law, resistance-current relationships, current control through lamps, coils and resistive loads, and series-circuit measurement exercises.
