8. The insulation resistance between the internal circuit of the resistance box and the metal part of the shell is greater than 20MΩ

Function:

The resistance box is designed and produced according to the requirements of the textbooks compiled by the Ministry of Education of China. It is mainly used as a standard resistor in physics teaching to verify Ohm's law, or as an additional anode to expand the range of ammeters and voltmeters. It can also be used to measure unknown resistance and as a variable resistor to connect to electronic circuits to adjust the required working point current and voltage. At the same time, the resistance box can also be used to measure the electromotive force of the power supply and the internal resistance of the power supply. It is an indispensable instrument in physical electrical experiments.

Use:

The resistance box is made of metal sheet and aluminum alloy frame, with a sealed structure. The transformation of each group and each gear resistance is in the form of a band switch. The purpose of changing the resistance value is achieved by rotating the contact switch to different positions. The low value part of the internal resistance is wound with high stability constantan wire in a non-inductive winding method, and the high resistance part uses precision special metal film resistors. After strict screening, testing, aging, and impregnation treatment, the resistance value is stable and correct. In short, the resistance box has a wide range of applications in physics teaching. It can not only help students learn and understand the properties of resistance and the working principle of circuits, but also can be used for experimental operation and measurement. It is one of the indispensable instruments in physics laboratories.
