Rheostat 12 Inches Manufacturer,Supplier and Exporter in India
Product Code : SCL-EAE-11280
The Rheostat 12 Inches changes the effective resistance in a circuit by moving a sliding contact along a resistance element. As the active resistance changes, the current flowing through the connected circuit can be increased or decreased within the permitted electrical limits.
The stated 12-inch capacity identifies the nominal length designation of the rheostat. The exact resistance range, resistance-wire material, current rating, terminal arrangement, tube construction and overall dimensions must be confirmed from the approved product specification before publication or procurement.
Key Features
12-inch laboratory format: Provides a nominal 12-inch rheostat configuration for educational circuit experiments.
Variable resistance control: Allows gradual adjustment of the effective resistance through a movable contact.
Current-control learning: Demonstrates how increasing or decreasing resistance changes circuit current.
Supports quantitative experiments: Can be used with suitable meters to compare voltage, current and resistance readings.
Visible operating principle: Helps students understand the relationship between slider position and active resistance.
Reusable laboratory apparatus: Suitable for repeated supervised practical work when used within its confirmed rating.
Compatible teaching component: Can be integrated with suitable power supplies, switches, lamps, resistors and measuring instruments.

How to Use the Rheostat 12 Inches
Place the rheostat on a clean, dry and stable laboratory bench.
Check its confirmed resistance and maximum current ratings.
Move the slider to the position that introduces the highest suitable resistance.
Keep the power supply switched off while assembling the circuit.
Connect the correct rheostat terminals according to the experiment diagram.
Switch on the low-voltage supply and move the slider gradually.
Observe the corresponding change in current, voltage or lamp brightness.
Switch off the supply before changing connections or removing the apparatus.
Safety note: Do not exceed the confirmed current or power rating. The resistance element may become hot during use. Avoid touching it until the power is disconnected and the unit has cooled.
Care & Maintenance
Store the rheostat in a dry, dust-free laboratory cabinet.
Keep the resistance element, slider and terminals free from dirt and corrosion.
Move the slider gently without forcing it against the end stops.
Inspect the winding, contacts and terminal connections before each experiment.

Frequently Asked Questions
What is a Rheostat 12 Inches used for?
It is used to vary electrical resistance and control current in a compatible laboratory circuit.
How does a sliding rheostat work?
A movable contact changes the effective length of resistance wire included in the circuit. Changing that length changes the resistance and therefore affects current flow.
Can this rheostat be used for Ohm’s law experiments?
Yes. It can help vary circuit current when used with a suitable resistor, regulated power supply, ammeter and voltmeter.
What is the resistance rating of this rheostat?
The resistance value has not been supplied. Confirm the required resistance in ohms and the permitted current rating before ordering.
Is the Rheostat 12 Inches suitable for schools?
Yes. It is intended for supervised electrical experiments in schools, colleges and introductory technical laboratories.
Why can a rheostat become hot?
A rheostat dissipates electrical energy as heat while carrying current. Excessive current or prolonged use can cause overheating and damage.
Request the confirmed resistance and current rating from Lab Exports, or browse the Electrical and Electronics Laboratory Equipment category. Compatible measuring options are available in the Laboratory Meters range, including the Digital LCD Ammeter.
