10 2A Slide Rheostat Science & Discovery Toys For Experiment

Description:
It is an experimental facility for children to experiment and learn thePhysics, it can slide resistance.
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 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 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 reasons, it may appear screw loose, loose slider and illnesses , pay attention to check eliminated. 3 , rheostat should not exceed the rated maximum load.
Package included:
1x slide rheostat
1x manual
