Product Code : SCL-EAE-11312
The Wire-Wound Adjustable Resistor 1.6A is a laboratory rheostat used to vary resistance and control current in low-voltage electrical circuits. Its sliding contact enables students and instructors to adjust circuit conditions continuously and use the apparatus as either a variable resistor or potential divider.
Product Description
The apparatus uses electrically oxidized Constantine, also known as Eureka wire, wound around an insulated heat-resistant porcelain tube. A movable contact travels along the winding and changes the effective length of resistance wire included in the circuit. Increasing the active wire length increases resistance, while reducing it lowers resistance.
Lab Equipments Ambala publishes the corresponding rheostat under product code EL-EAE-10287 with available current ratings from 0.6 A to 8 A. The requested 1.6 A configuration must be paired with a confirmed resistance value because rheostats with the same current rating may be manufactured in different resistance ranges.
Key Features
- 1.6 A current configuration: Requested rating falls within the manufacturer’s published 0.6 A to 8 A range.
- Wire-wound resistance element: Constantine or Eureka wire is wound on an insulated porcelain tube.
- Smooth sliding adjustment: A phosphor-bronze contact changes the effective resistance continuously.
- Double-contact slider: Supports consistent contact with the resistance winding during adjustment.
- Three brass terminals: Allows use as a two-terminal rheostat or three-terminal potential divider.
- Heat-resistant support: Porcelain construction assists insulation and heat dissipation.
- Laboratory-grade mechanism: A heavy brass contact block supports smooth movement and repeated use.

How to Use the Wire-Wound Adjustable Resistor 1.6A
- Switch off the circuit power before making connections.
- For current control, connect the slider terminal and one end terminal in series with the load.
- Set the slider initially to provide maximum practical resistance.
- Switch on the low-voltage supply.
- Move the slider gradually while observing the circuit current.
- Keep the current at or below the confirmed 1.6 A rating.
- Switch off the supply before changing terminals or circuit configuration.
Safety note: The resistor can become hot during operation. Do not touch the winding or porcelain tube immediately after use, exceed the 1.6 A rating, or connect the apparatus directly to an unsuitable mains supply.
Care & Maintenance
- Keep the resistance winding clean and free from conductive debris.
- Move the slider gently and do not force it over damaged winding.
- Check terminals, supports and contact pressure periodically.
- Allow the resistor to cool before handling or storage.

Frequently Asked Questions
What is a Wire-Wound Adjustable Resistor 1.6A used for?
It is used to vary resistance, control current and divide voltage in low-voltage educational circuits.
Is this component a rheostat?
Yes. Its sliding contact changes the active length of resistance wire and therefore changes circuit resistance.
What resistance value is supplied?
The resistance value is not specified by the 1.6 A rating alone and must be confirmed separately in ohms.
Can it be used as a potential divider?
Yes. The three-terminal arrangement permits potential-divider operation when all terminals are connected correctly.
What wire is used in the resistor?
The published product uses electrically oxidized Constantine, also called Eureka resistance wire.
Can the resistor carry more than 1.6 A?
No. The selected 1.6 A variant should not be operated above its confirmed continuous current rating.
Specify the required resistance in ohms together with the 1.6 A current rating, or explore the Electrical and Electronics Equipment category for related circuit apparatus.
