Rheostat 125 OHM
Product Code : JA-EE-7509
The Rheostat 125 OHM (SKU JA-EE-7509) is a 125 ohm sliding rheostat used to vary current or tap off a variable voltage in school and college electricity practicals. This 125 ohm rheostat for the physics lab has heavily oxidised resistance wire wound on a vitreous enamel steel tube between die-cast end stands, a nickel-plated heavy-duty slider and 4 mm terminal posts. JaincoLab supplies it among rheostats from 2.5 to 1600 ohm.
Specifications
The Rheostat 125 OHM gives up to 125 ohm through a winding of heavily oxidised resistance wire on a vitreous enamel steel tube, mounted on die-cast end stands, with a corrosion-resistant nickel-plated sliding contact and 4 mm terminal posts; its current rating is confirmed on the quotation.

Applications of the 125 ohm rheostat
A mid-range 125 ohm rheostat suits circuits with modest currents: students use it as a variable resistor to set the current in Ohm's law and meter experiments, or as a potential divider to supply a variable voltage to components and sensors.
- Setting current in Ohm's law experiments
- Potential divider supply for components and sensors
- Current control for meters and galvanometers
- Diode and LED characteristic experiments
- Senior-school and college electricity practicals
