Product Name: 

0-99999 Resistance Box Instrument for physical electrical experiments J15026-1

I. Overview
J15026-1 resistance box is designed and manufactured according to the requirement of "Catalogue of Instruments for Science Teaching in Middle Schools" issued by the State. It is mainly used as standard resistance in physics teaching to verify Ohm's law, or as additional resistance to expand the range of ammeter and voltmeter. It can also be used to measure unknown resistance and to connect variable resistance to electronic circuit to regulate the working point current and voltage. The time resistance box can also be used to measure the EMF and internal resistance of the power supply. It is an indispensable instrument in physical and electrical experiments.

Because the resistance box is made of metal shell structure, it has little external influence, strong anti-interference ability and very stable resistance value.
