0-9999.9 Ohm Variable Resistance Box Decade Resistor Equipment For Physical Resistance Box Laboratory Tool Features: 1.100% new and high quality product. 2. Can verify part of Ohm's law of the circuit. 3. Used as an additional resistor to extend the voltage range. 4. Used to measure unknown resistance. 5. Used as electromotive force and internal resistance to measure power supply. 6. Used as a known resistance in the circuit to adjust the required current.

product description 23022 teaching resistance box is used for ordinary middle school, technical secondary school and college students to conduct the following electrical experiments: to verify part of the circuit Ohm's law: used as an additional resistance to expand the range of the voltmeter; used to measure unknown resistance: used to connect known resistance to the circuit To adjust the required current; used to measure the electromotive force and internal resistance of the power supply, etc. It is an indispensable instrument in electrical experiments. Structure and usage The 23022 teaching resistance box adopts bakelite sealed structure. The resistance value conversion method is in the form of a knob switch, which relies on the brush to rotate to different positions to achieve the purpose of resistance value conversion. Panel layout, circuit principle. The resistance element of this instrument is made of highly stable precision alloy manganese-copper wire which is non-inductively wound on the porcelain skeleton. After strict screening, testing, aging and dipping treatment, the resistance value is stable and correct. When in use, connect it to the circuit through the two binding posts on the panel, and adjust the five knobs to get a certain resistance value in 0 999.92. The readings of the indication points of each knob are multiplied by the above multiples and added to form the resistance indication value. Generally, the value of the indication points of each knob is read in order from high multiples to low multiples. This value is the resistance indication value. The resistance is 5083.2.

Product parameters: 1. Accuracy level: Level 1. 2. Adjustable resistance range: 0~9992, the minimum step value is 0.10. 3. Operating temperature: 0~40 C. 4. Relative temperature: 25%< 80%. 5. Zero resistance: Ro < 0.03502. ; 6. Reference power: 0.5W; rated power: 1W. 7. Volume: 165x125x60 1000000 8. The insulation resistance between the circuit and the metal part of the shell is > 50M0.
