Key Features
- Slide wire rheostats with a non inductive, non magnetic core, reducing magnetic effects by more than 90 percent
- Wires are heavily oxidised to provide insulation
- Standard grooved type wound with Eureka wire on a 5.6 cm diameter tube, with grooves to avoid loosening of the wire
- Nichrome wire version on a 5.6 cm diameter tube, described as suitable for high current
- Brushes of hard laminated brass and phosphor bronze strips
- Single phase loading rheostats with tumbler switches for load in equal steps, a control switch with fuses and two insulated terminals

About This Product
A rheostat is a variable resistor that changes the current in a circuit when a sliding contact is moved along a resistance wire. In school physics it is used in Ohm's law, meter bridge and potentiometer experiments to vary current or voltage. The grooved winding keeps the wire in place as the slider moves, nichrome wire suits higher current, and a loading rheostat gives a load in equal steps for tests on a supply. The Slide Wire Rheostats can be supplied and exported to buyers in Kyrgyzstan, Latvia, Iceland, Mauritius, Botswana and Mexico.
Frequently Asked Questions
Q1. What wire is used in the grooved rheostats?
