Electrical Engineering Rheostat Manufacturer,Supplier and Exporter in India

Product Code : SCL-EE-12720

The Electrical Engineering Rheostat is a variable-resistance laboratory apparatus used to control current in low-voltage electrical circuits for Ohm’s law, resistance variation, voltage-drop study, current limiting, and circuit-training experiments. It is suitable for schools, colleges, engineering labs, physics labs, STEM classrooms, distributors, and institutional procurement teams.

Product Description

Electrical Engineering Rheostat from School Equipments India is intended for supervised physics and electrical engineering practicals. A rheostat works as an adjustable resistor in a circuit, allowing students to change resistance and observe the resulting effect on current. Exact resistance range, current rating, power rating, winding material, tube length, slider mechanism, terminal type, dimensions, and calibration status must be confirmed from the final supplied product.

This apparatus helps learners connect electrical theory with measurable circuit behaviour. It supports practical work on Ohm’s law, variable resistance, series circuits, current control, voltage-current relationships, and safe circuit adjustment. It should not be described as a precision calibration instrument unless valid calibration documentation is supplied.

Key Features

• Variable-resistance function: used to adjust resistance during supervised electricity and circuit practicals.
• Current-control teaching aid: helps students observe how current changes when resistance is varied.
• Ohm’s law support: suitable for voltage, current, and resistance relationship demonstrations.
• Electrical training value: useful for wiring practice, meter reading, and circuit response observation.
• Low-voltage lab use: intended for school, college, and engineering training circuits under supervision.
• Construction to confirm: slider, coil winding, tube, base, terminals, and insulation details must be verified.
• Ratings to confirm: resistance range, current limit, power rating, and tolerance should be checked before procurement.

How to Use the Electrical Engineering Rheostat

1. Check the product label, resistance range, current rating, terminals, and experiment instructions before use.
2. Keep the power supply switched off while making circuit connections.
3. Connect the rheostat in the required circuit position using suitable laboratory leads.
4. Set the slider or control to the safe starting position recommended by the teacher.
5. Switch on only the approved low-voltage laboratory supply.
6. Move the slider gradually and observe ammeter and voltmeter readings.
7. Record readings at different resistance settings without exceeding the confirmed rating.
8. Switch off the supply before disconnecting, repositioning, or storing the apparatus.

Safety note: Use only under teacher or laboratory-supervisor control. Do not overload the rheostat, connect it directly to mains voltage, touch terminals during live experiments, or continue use if heating, sparking, burning smell, or unstable readings occur.

Care & Maintenance

• Store in a dry, dust-free cabinet after practical sessions.
• Keep slider contacts, terminals, tube surface, and connection points clean and corrosion-free.
• Do not exceed the confirmed current, voltage, or power rating.
• Quarantine the apparatus if the slider is loose, winding is damaged, terminals overheat, or readings become unstable.
