Rheostat 10 Inches Manufacturer,Supplier and Exporter in India
Product Code : SCL-EAE-11281
The Rheostat 10 Inches uses a sliding contact that moves along a resistance element. Moving the slider changes the length of resistance wire included in the circuit. A longer active wire length provides greater resistance, while a shorter active length provides lower resistance.
The apparatus gives students a visible method of adjusting circuit resistance during electricity experiments. Its mounted format supports demonstrations on a laboratory bench and repeated practical work. The resistance value, permissible current and construction materials must be verified for the selected model before use.
Key Features
10-inch laboratory size: Provides the stated apparatus length for classroom and laboratory demonstrations.
Variable resistance control: Changes the effective resistance through movement of the sliding contact.
Regulates circuit current: Helps learners observe how increased resistance reduces current under controlled conditions.
Visible operating principle: Makes the relationship between wire length, resistance and current easier to explain.
Accessible electrical terminals: Allows connection to suitable meters, power supplies and circuit components.
Stable instructional format: Supports teacher demonstrations and supervised student measurements.
Reusable laboratory apparatus: Suitable for repeated experiments when operated within its confirmed ratings.

How to Use the Rheostat 10 Inches
Place the rheostat on a stable, dry and non-conductive bench.
Inspect the resistance element, slider and terminals for damage.
Switch off the electrical supply before making connections.
Connect one fixed terminal and the sliding-contact terminal as required.
Position the slider for maximum resistance before switching on.
Energise the circuit and move the slider gradually.
Record the corresponding current or voltage readings.
Switch off the supply before changing the circuit arrangement.
Safety note: Do not exceed the confirmed current or power rating. The resistance element can become hot during use. Avoid touching it, short-circuiting the circuit or forcing the slider.
Care and Maintenance
Disconnect the rheostat from the circuit after every experiment.
Keep the resistance element, slider and terminals clean and dry.
Move the sliding contact gently to minimise wear and misalignment.
Allow the apparatus to cool before storing it in a dry cabinet.

Frequently Asked Questions
What is a Rheostat 10 Inches used for?
It is used to vary resistance and regulate current in an electrical circuit by changing the position of a sliding contact.
How does a sliding rheostat control current?
Moving the slider changes the active length of resistance wire. Increasing the active length raises resistance and normally reduces circuit current.
Can this rheostat be used for Ohm’s law experiments?
Yes. It can be used to adjust current while students measure voltage and current at different circuit conditions.
What resistance value does this model provide?
The resistance value has not been supplied. Buyers should confirm the resistance range and current rating before ordering.
Can the resistance element become hot?
Yes. A rheostat dissipates electrical energy as heat, particularly during prolonged use or at higher current levels.
Is the Rheostat 10 Inches suitable for schools?
Yes. It is suitable for supervised school, college, polytechnic and vocational electricity experiments within its confirmed ratings.
