Rheostat 8 Inches Manufacturer,Supplier and Exporter in India
Product Code : SCL-EAE-11282
The Rheostat 8 Inches controls current by changing the effective length of resistance wire connected within a circuit. Moving the sliding contact changes the resistance between the selected terminals, allowing users to observe how resistance affects current and voltage.
The compact 8-inch format is suitable for classroom demonstrations and student practical work. The resistance value, current rating, resistance-wire material, tube construction, terminal arrangement and dimensional basis of the 8-inch designation must be confirmed from the approved specification before publication or procurement.
Key Features
8-inch laboratory format: Provides a compact variable-resistance unit for educational circuit experiments.
Adjustable resistance: A movable contact changes the effective resistance included in the circuit.
Current-control function: Helps demonstrate how increased resistance reduces current under suitable circuit conditions.
Visible operating principle: Allows students to relate slider position to changes in circuit behaviour.
Supports practical measurement: Can be used with compatible ammeters and voltmeters to record electrical values.
Reusable teaching apparatus: Suitable for repeated laboratory sessions when operated within its confirmed rating.
Simple circuit integration: Connects with suitable low-voltage supplies, switches, leads and experimental loads.

How to Use the Rheostat 8 Inches
Place the rheostat on a clean, dry and stable laboratory bench.
Check the confirmed resistance and maximum current ratings.
Move the slider to a position that introduces high resistance.
Keep the power supply switched off while making connections.
Connect the correct terminals according to the experiment diagram.
Switch on the low-voltage supply and move the slider gradually.
Observe and record the corresponding current or voltage readings.
Switch off the supply before changing connections or removing the apparatus.
Safety note: Do not exceed the confirmed current or power rating. The resistance winding may become hot during operation. Disconnect the supply and allow the unit to cool before touching or storing it.
Care & Maintenance
Store the rheostat in a dry, dust-free laboratory cabinet.
Keep the resistance winding, slider and terminals clean.
Move the slider gently and do not force it against the end stops.
Inspect the winding, contacts and terminal connections before use.

Frequently Asked Questions
What is a Rheostat 8 Inches used for?
It is used to vary resistance and control current in a compatible educational electrical circuit.
How does a sliding rheostat work?
The slider changes the effective length of resistance wire included in the circuit. This changes the resistance between the selected terminals.
Can this rheostat be used for an Ohm’s law experiment?
Yes. It can vary circuit current when used with a suitable power supply, fixed resistor, ammeter and voltmeter.
What is the resistance rating of the rheostat?
The resistance value and maximum current rating have not been supplied. Both specifications must be confirmed before ordering or use.
Is the Rheostat 8 Inches suitable for school laboratories?
Yes. It is intended for supervised electrical experiments in schools, colleges and introductory technical laboratories.
Why does a rheostat become hot?
A rheostat dissipates electrical energy as heat while carrying current. Excessive current or prolonged operation may overheat the resistance winding.
