Specifications:?

The kit includes 5 rheostats: 0-5 ohms, current 3 A; overall size 52x95x230mm; 0-10 ohms, current 2A. Overall size 175x35x60mm; 0-50 ohms, force current is 1.5A. Overall size 52x95x230mm; 0-200 ohms, current 1.5A. Overall size 90x145x260mm; 0-1750 ohms, current strength is 1.5A. Overall size 92x145x330mm

Function:

This rheostat is used in laboratory research, used to change voltage and current in the calibration of electrical instruments or as a substitute for variable resistors of undetermined resistance, and used for demonstration by middle school physics teachers or group experiments by students in teaching.

Application:?

The sliding rheostat is composed of alloy wire porcelain tube, sliding head, sliding rod, bracket, terminal and other main parts. It uses copper-nickel alloy resistance wire with oxide film insulation layer tightly wound on the porcelain tube. There is a conductive brush on the surface of the resistance wire that can slide on the wire surface. It is a device that changes the resistance by changing the length of the wire, and an instrument that changes the voltage and current by changing the resistance.
