Rheostat 8.5 ohm
Product Code : JA-EE-7531
The Rheostat 8.5 ohm (SKU JA-EE-7531) is a low-value sliding rheostat for varying current in lamp, coil and resistance-wire circuits on low-voltage supplies in school and college electricity practicals. This 8.5 ohm rheostat is wound with heavily oxidised resistance wire on a vitreous enamel steel tube between die-cast end stands, with a nickel-plated heavy-duty contact and 4 mm terminal posts. JaincoLab supplies it with the other values in its rheostat range.
Specifications
The Rheostat 8.5 ohm provides up to 8.5 ohm from heavily oxidised resistance wire wound on a vitreous enamel steel tube with die-cast end stands, a heavy-duty sliding contact nickel plated against corrosion and 4 mm terminal posts; its current rating is confirmed on the quotation.
