Description

Description:
It is an experimental facility for children to experiment and learn the Physics, it can slide resistance.
Item: Slide Rheostat
Size: about 16cm

Usage:

1. When the current in the circuit is used to adjust the intensity , it should slide rheostat in series with the circuit, and the first raised to the maximum slip resistance rheostat , connect the power supply , then slide the conductive brush , gradually reducing resistance , so that the current strength suitable amount is gradually increased .
2. When used to adjust the voltage of the circuit between two points , and the circuit should varistor connected in parallel , and the first rheostat resistance to minimum , connect the power supply , then slide the conductive brush , and gradually increase the resistance , the circuit ends voltage is gradually increased to the appropriate value.

Note:

1. when the rheostat use should not be too close to the heat source.
2. rheostat long-term use may cause poor contact oxidation insulation in contact with the resistance wire brush , then wipe away the oxide layer must be used. Long love vibration and other reasons, it may appear screw loose, loose slider and other illnesses , pay attention to check eliminated.
3. rheostat should not exceed the rated maximum load.

Package Included:
1x Slide Rheostat
