Home / Product / Physics teaching instruments / New style sliding rheostat adjustable physical electrical resistance equipment
Product Overview

Model:

X0047

Application area:

Physical electrical experimental equipment teaching instruments

Important parameters:

Material: metal + plastic + ceramic

1. Resistance error does not exceed ±10% of standard resistance

2. Insulation can withstand AC 50HZ, 2850V test voltage

3. Insulation resistance is 60-70% at temperature +20℃±5℃ and relative temperature, not less than 10 megohms

Function:

Sliding rheostat is used in laboratory research, used to change voltage and current in calibrating electrical instruments or as a substitute for variable resistors of uncertain resistance.

Use:

Sliding rheostat has multiple functions in the circuit, such as protecting the circuit, changing the voltage at both ends of the resistor, controlling the voltage unchanged, changing the voltage at both ends of the bulb, changing the current size and direction, etc. It can realize precise control and regulation of the circuit and improve circuit performance and stability
