Sliding Rheostat Dual Tube Manufacturer,Supplier and Exporter in India
Product Code : SCL-EAE-11279
The apparatus uses two cylindrical resistance-tube sections mounted on a stable laboratory base. A movable contact travels along the resistance arrangement, changing the effective length of resistance wire included in the circuit. A longer active resistance path produces greater resistance, while a shorter path produces lower resistance.
The dual-tube format provides a visible and accessible arrangement for electricity demonstrations. Connection terminals allow the rheostat to be incorporated into suitable low-voltage circuits. The exact resistance range, current rating, winding material, tube material and terminal configuration were not supplied and must be confirmed before ordering.
Key Features
Dual-tube configuration: Provides two mounted resistance sections in a compact instructional apparatus.
Variable resistance control: Changes effective resistance through movement of the sliding contact.
Current regulation: Helps students observe how resistance controls current in a closed circuit.
Visible operating principle: Makes the relationship between resistance length and circuit behaviour easier to demonstrate.
Accessible terminals: Supports connection to suitable power supplies, meters and experiment components.
Stable laboratory base: Keeps the apparatus supported during classroom demonstrations and student practicals.
Reusable teaching equipment: Suitable for repeated electrical experiments when operated within its confirmed ratings.

How to Use the Sliding Rheostat Dual Tube
Place the apparatus on a stable, dry and non-conductive bench.
Inspect the resistance tubes, slider and terminals for damage.
Switch off the circuit supply before making any connections.
Connect the required fixed terminal and sliding-contact terminal.
Position the slider for maximum resistance before energising the circuit.
Switch on the supply and move the slider gradually.
Record the corresponding current or voltage readings.
Switch off the supply before changing the circuit connections.
Safety note: Do not exceed the confirmed current or power rating. The resistance element may become hot during use. Avoid touching it, short-circuiting the apparatus or forcing the sliding contact.
Care and Maintenance
Disconnect the apparatus after every experiment.
Keep the resistance tubes, slider and terminals clean and dry.
Move the contact gently to prevent wear or misalignment.
Allow the apparatus to cool before storing it in a dust-free cabinet.

Frequently Asked Questions
What is a Sliding Rheostat Dual Tube used for?
It is used to vary resistance and control current in electrical experiments by changing the position of a sliding contact.
How does a sliding rheostat change resistance?
Moving the slider changes the effective length of resistance wire in the circuit. Increasing the active length increases resistance.
Why does this rheostat have two tubes?
The dual-tube arrangement provides two mounted resistance sections. The exact electrical relationship between them depends on the supplied terminal and winding configuration.
Can it be used for Ohm’s law experiments?
Yes. It can regulate current while students measure voltage and current at different circuit conditions.
Can the resistance tubes become hot?
Yes. Electrical energy can be dissipated as heat, particularly at higher currents or during prolonged operation.
Is the Sliding Rheostat Dual Tube suitable for schools?
Yes. It is suitable for supervised school, college, polytechnic and vocational electricity experiments within its confirmed ratings.
