Rheostat 2.5 ohm
Product Code : JA-EE-7517
The Rheostat 2.5 ohm (SKU JA-EE-7517) is the lowest-value sliding rheostat in the range, used for fine adjustment of current in low-resistance circuits during school and college electricity practicals. This 2.5 ohm rheostat has heavily oxidised resistance wire wound on a vitreous enamel steel tube held by die-cast end stands, with a nickel-plated heavy-duty slider and 4 mm terminal posts. JaincoLab supplies it to physics laboratories.
Specifications
The Rheostat 2.5 ohm offers a total of 2.5 ohm from a winding of heavily oxidised resistance wire on a vitreous enamel steel tube with die-cast end stands, a heavy-duty sliding contact nickel plated for corrosion resistance, and 4 mm terminal posts; its current rating is confirmed on the quotation.

Applications of the 2.5 ohm rheostat
A 2.5 ohm rheostat changes resistance in small steps, so it is used where a circuit already has low resistance, for example trimming the current through a coil, electromagnet or low-voltage lamp, or setting the load on a cell when its internal resistance is measured.
- Trimming current through coils and electromagnets
- Adjusting brightness of low-voltage filament lamps
- Variable load for measuring the internal resistance of a cell
- Fine current adjustment in low-resistance circuits
- Class sets of low-value rheostats
