PRINCIPLE OPERATION: Slide rheostat resistance can be used to control the function of a circuit by changing its own resistance.
DUAL USE: The laboratory researching tool can be used as a constant/variable resistor to meet different circuit analysis needs.
APPLICATIONS: Sliding rheostat can be used as a current and voltage regulator for laboratory research and demonstration, as well as for excitation and speed control of power generation equipment and DC motors.
SAFETY AND RELIABILITY: The sliding head and insulated wiring hat are designed for safe and reliable use and are suitable for teaching physics and electricity.
DURABILITY: Alloy wire porcelain tube and contact copper sheet, exquisite workmanship, durability, and long service time.
