Educational Current Regulator 8"

Product Code : SCL-EAE-11316

The Educational Current Regulator 8 Inch is a laboratory rheostat used to vary resistance and regulate current in low-voltage electrical circuits. Its movable contact changes the active length of resistance wire, enabling continuous adjustment during school, college and introductory electrical experiments.

Product Description

The current regulator consists of resistance wire wound around an insulated, heat-resistant tube. A sliding contact moves along the winding and selects the effective length of wire included in the circuit. Increasing the active length raises resistance and reduces current, while shortening it lowers resistance and permits more current to flow.

The requested apparatus has an 8-inch designation, but the dimensional reference requires confirmation. The closest published Lab Equipments Ambala rheostat uses Constantine or Eureka wire, a porcelain tube, three brass terminals and a phosphor-bronze double-contact slider. The required resistance and current rating must be selected for the intended circuit.

Key Features

• 8-inch configuration: Requested compact laboratory size; exact tube, winding or overall dimension.
• Continuous current regulation: The sliding contact changes resistance smoothly during operation.
• Wire-wound resistance element: Provides adjustable resistance for educational circuit experiments.
• Potential-divider capability: A suitable three-terminal layout permits adjustable voltage output.
• Heat-resistant support: The closest published model uses a special porcelain tube.
• Double-contact slider: The related Constantine-wire rheostat uses phosphor-bronze contacts for consistent movement.
• Manual operation: Requires no independent power source beyond the experimental circuit.

How to Use the Educational Current Regulator 8 Inch

1. Switch off the low-voltage laboratory power supply.
2. For current regulation, connect one winding-end terminal and the slider terminal in series with the load.
3. Set the slider initially to provide a high resistance.
4. Switch on the supply while monitoring the circuit current.
5. Move the slider gradually until the required current is obtained.
6. For potential-divider use, connect the supply across both winding ends and take the output from the slider.
7. Keep current and power within the confirmed apparatus ratings.
8. Switch off the supply before changing connections.

Safety note: The resistance winding and support tube can become hot during operation. Do not touch them immediately after use, exceed the confirmed current rating or connect the regulator directly to an unsuitable mains supply.

Care & Maintenance

• Keep the resistance winding clean and free from conductive debris.
• Move the slider smoothly without forcing it across damaged wire.
• Inspect terminals, fasteners and contact pressure periodically.
• Allow the regulator to cool fully before handling or storage.

Frequently Asked Questions

What is an Educational Current Regulator 8 Inch used for?

It is used to vary resistance, regulate current and provide adjustable voltage in low-voltage educational circuits.

What does the 8-inch measurement refer to?

It may refer to the resistance tube, winding length, slider travel or overall nominal size. The exact dimensional reference must be confirmed.

What resistance value is supplied?

The resistance value is not determined by the 8-inch designation and must be selected separately in ohms.

Which resistance wire is used?

The closest published model uses Constantine or Eureka wire, but the alloy for this exact 8-inch configuration requires confirmation.

Can it be used as a potential divider?

Yes, provided the apparatus has access to both ends of the winding and the sliding-contact terminal.

Does the current regulator require its own power supply?

No. It is a passive component that operates within a suitable low-voltage experimental circuit.
