Features:
1.It can verify Ohm's law of some circuits.
2.Used as an additional resistor to expand the volt range.
3.Used to measure unknown resistance.
4.Used for measuring the electromotive force and internal resistance of the power supply.
5.Used as a known resistor in a circuit to regulate the required current. Used for teaching physical and electrical experiments.
Product Overview
J15026-2 resistance box is designed and produced according to the requirements of textbooks compiled by the Ministry of Education of the People's Republic of China. It is mainly used in physics teaching as a standard resistance to verify Ohm's law, or as an additional resistance to expand the range of Ammeter and Voltmeter. It can also be used to measure unknown resistance and as a variable resistance to access electronic circuits to adjust the required current and voltage at the working point. At the same time, the resistance box can also be used to measure the electromotive force and internal resistance of the power supply. It is an essential instrument in physical electrical experiments.
Structural Principles
The resistance box is made of metal sheet and aluminum alloy frame, with a sealed structure. The resistance of each group and each level is converted into a band switch form, relying on the contact switch to rotate to different positions to achieve the purpose of changing the resistance value. The low value part of the internal resistance is wrapped with high stability copper wire using non-inductive winding method, while the high resistance part is made of precision specialized metal film resistance. After strict screening, testing, aging, and soaking treatment, the resistance value is stable and correct.
Parameters:
Type: Resistance box
Model: 15026
Measurement range: 0~999999 Ω
Reference power: 0.5W
Operating temperature: 15-30 ℃
Color: Black
Material: Plastic
The insulation resistance between the internal circuit of the resistance box and the metal part of the casing is greater than 20MQ.
Usage:
Connect the two terminals to the circuit or measuring instrument (such as a multimeter), adjust the corresponding knobs to obtain the required resistance value. The readings indicated by each knob indicator point are multiplied by the corresponding multiples (X100K, X10K, X1K, X100, X100, X1) and added together to obtain the total resistance value of the corresponding position of the knob in the resistance box.
Package include:
Resistance box * 1
