Durable construction for reliable control - The sliding rheostat uses oxidised and insulated wire tightly wound on a porcelain tube and attached to a metal bracket for sturdy, long-term operation. Precise, simple regulation - The slide rheostat functions as a control element by changing its own resistance, enabling accurate regulation of current and voltage in a circuit. Versatile applications for lab and equipment - This electric sliding rheostat can serve as a current and voltage regulator for laboratory research and demonstrations, and as excitation and speed control for power generation systems and DC motors. Key benefits - Robust, compact design with stable resistance adjustments - Easy integration into standard lab setups and demonstrations - Material fidelity: porcelain tube, oxidised insulated wire, and metal bracket ensure durability and performance Use scenarios - In a research bench to regulate current/voltage during experiments - In a small generator system to control excitation and output - In educational demonstrations to adjust DC motor speed by varying resistance Performance and compatibility - Function: adjustable resistance to control current and voltage - Material: oxidised insulated wire, porcelain tube, metal bracket - Size: compact, suitable for bench setups and standard test rigs - Application: laboratory regulation, power generation excitation, DC motor speed control
