About This Product
Moving the slider changes how much of the winding is in circuit: more active wire gives more resistance, less gives lower resistance. Connected through the slider and one end terminal in series with a load, it controls current for Ohm's law work, meter protection or adjusting lamp and electromagnet current; with all three terminals in use it becomes a potential divider. In Electrical And Electronics practicals the current must be kept at or below 1.6 A, and the winding can get hot during use.
Frequently Asked Questions
Q1. Can the Wire-Wound Adjustable Resistor 1.6A be used as a potential divider?
Yes. Its three-terminal arrangement allows potential-divider operation when all three terminals are connected correctly.
Q2. Which resistance wire does it use?
Electrically oxidised Eureka resistance wire, wound on an insulated, heat-resistant porcelain tube.
Q3. Does the 1.6 A rating set the resistance value?
No. Rheostats with the same current rating are made in different resistance ranges, so the resistance in ohms is specified separately from the 1.6 A rating.
