Product Description Product DescriptionSliding Rheostat Teaching Instrument for Physics Education 20Ω 2A small Intriguing Product IntroductionSliding rheostat physics teaching equipment is a meticulously engineered device comprising essential components such as a wire-wound porcelain tube, dynamic sliding head, smooth sliding rod, sturdy bracket, and reliable terminals. Crafted with precision, it employs a copper-nickel alloy resistance wire, elegantly insulated with an oxide film layer, and carefully wound on a robust porcelain tube. A conductive brush glides effortlessly over the wire surface, allowing for seamless resistance adjustment, ultimately altering voltage and current with precision and ease.Comprehensive Product Specification DetailsResistance value(Ω)Rated current(A)0~1020~200~501.50~2001.250~53The varistor's resistance value maintains a precision accuracy, with an error margin not exceeding ±10%, ensuring reliable performance.Engineered for robust operation, the varistor functions continuously between -10°C to +40°C with humidity levels below 85%, ensuring adaptability across diverse environments.* Scale length elegantly marked on the slide rheostat: 0-100mm for precise measurements.* Porcelain pipe diameter: 45mm, ensuring durability.* Adjustable slide block, extending from 0-100mm for versatile applications.* Carbon brush ensures smooth and reliable slide contact. * Customizable slide rheostat available with diverse resistance and amperage options as follows:10Ω, 5.6A; 180Ω, 2A; 333Ω, 0.95A for tailored applications.* Overall dimensions: 270mm × 95mm × 135mm, compact yet efficient.Product Features and Versatile ApplicationsThis sliding rheostat is indispensable for lab research, testing, and in standard electrical instruments to dynamically modify voltage and current or serve as a versatile variable resistor. It is a vital tool for middle school physics teachers to effectively demonstrate principles or for students to engage in enriching group experiments.Maintenance and Important Precautions1. Ensure the varistor is kept away from heat-sensitive objects to avoid damage.2. If unused for extended periods, the contact point between the brush and resistance wire may develop an oxidized layer, hindering performance. Clean before use. Regular checks are recommended to secure screws and sliding heads, preventing issues caused by prolonged vibrations.3. It is crucial not to exceed the varistor's rated maximum load to ensure safety and longevity.Detailed PhotosCompany ProfileCertificationsPackaging & ShippingFAQ
