Sliding Rheostat Equipment for Physics Education and Experiments 20Ω 2A Large
Product Introduction
SOur exquisite Sliding Rheostat Physics Teaching Equipment is expertly crafted, featuring essential components like a wire-wound porcelain tube, sliding head, sliding rod, bracket, and terminal. The equipment boasts a copper-nickel alloy resistance wire tightly wound on the porcelain tube, with an insulating oxide film layer for perfect performance. A conductive brush glides effortlessly over the wire surface, adjusting wire length to alter resistance, and thereby modify voltage and current with precision.
Product Specification
| Resistance value(Ω) | Rated current(A) |
| 0~10 | 2 |
| 0~20 | |
| 0~50 | 1.5 |
| 0~200 | 1.25 |
| 0~5 | 3 |
Precision is key: The varistor's resistance value deviation remains within ±10%.
Engineered for endurance, the varistor performs continuously in temperatures from -10°C to +40°C and relative humidity up to 85%.
* Impeccable scale length on slide rheostat: 0-100mm
* Porcelain pipe diameter: 45mm ensures durability
* Slide block adjustability ranges a full 0-100mm
* Carbon brush for optimal slide contact

Product Feature and Application
Designed for versatility, this sliding rheostat serves in laboratory research and testing, standard electrical instruments for voltage and current adjustments, or as a variable resistor in place of undetermined values. It's a superb tool for middle school physics demonstrations and group experiments.
Maintenance and Precautions
1. Maintain a safe distance: Do not position the varistor near heat-sensitive objects.
2. Longevity care: If unused for extended periods, an oxidized insulating layer might form at the brush-resistance wire contact point. Remove this layer before operation. Address any loose screws or sliding heads caused by vibration or storage promptly.
3. Never exceed the varistor's rated maximum load to ensure lasting performance.
