Sliding Rheostat Physics Teaching Equipment - Slide Rheostat (23012)
Product Introduction
SThe sliding rheostat physics teaching equipment is an ingenious piece of educational apparatus, comprised of essential components such as a wire-wound porcelain tube, sliding head, sliding rod, bracket, and terminal. It elegantly employs a copper-nickel alloy resistance wire, intricately wrapped around a porcelain tube, with an oxide film insulating layer ensuring reliability. Featuring a conductive brush that glides effortlessly along the wire, this device masterfully adjusts resistance by altering the wire's length. Consequently, it adeptly modifies voltage and current, empowering educators and students to explore the principles of resistance for enhanced learning and experimentation.
Product Specification
| Resistance value(Ω) | Rated current(A) |
| 0~10 | 2 |
| 0~20 | |
| 0~50 | 1.5 |
| 0~200 | 1.25 |
| 0~5 | 3 |

Product Features and Applications
Our sliding rheostat physics teaching equipment is indispensable in laboratories for research and experimentation, seamlessly integrated into standard electrical instruments for voltage and current modulation, or employed as a variable resistor for dynamic resistance exploration. In educational environments, it serves as an invaluable tool for middle school physics teachers to demonstrate principles and for students to actively engage in group experiments, fostering a deeper understanding of electrical concepts.
Maintenance and Precautions
1. Ensure the varistor remains distant from heat-sensitive objects to prevent damage.
2. In cases of prolonged inactivity, the contact point between the brush and resistance wire may develop an oxidized insulating layer, leading to poor connection. This layer should be carefully removed before use. Additionally, check for and rectify loose screws or sliding heads caused by extended vibrations, ensuring secure storage.
3. Avoid exceeding the varistor's maximum rated load to maintain optimal functionality.
