0-9999.9 Ohm Variable Resistance Box Decade Resistor For Physical Resistance Box

Product features:
1. 100% brand new and high quality product.
2. Can verify part of the ohm's law of a circuit.
3. Used as additional resistors to extend the voltage range.
4. Used to measure unknown resistances.
5. Used as an electric potential and internal resistance to measure power supplies.
6. Used as a known resistor in a circuit to regulate the required current. Product Description
23022 teaching resistance box for general 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 extend the range of the voltmeter; used to determine the unknown resistance: used as a known resistance into the circuit to regulate the required current; used to measure the electric potential and internal resistance of the power supply, etc.. It is an essential instrument in electrical experiments.
Structure and use
The 23022 teaching resistance box has a sealed structure of rubber and wood. The resistance value change is in the form of a knob switch, which relies on the rotation of the brushes to different positions to achieve the purpose of resistance value change. Panel arrangement, wiring principle. The resistance element of this instrument is made of highly stable precision alloy manganese copper wire wound on a porcelain skeleton in a non-inductive way, which is strictly screened, tested, aged and impregnated for a stable and correct resistance value. When in use, the two terminals on the panel are connected to the circuit and the five knobs are adjusted to obtain a certain resistance value in 0 999.92. The reading of each knob to the indication point multiplied by the above multiplier is the resistance value, generally from high to low multiplier order to read out the value of each knob to the indication point, this value is the resistance value. The resistance is 5083.2. Product parameters:
1. Accuracy class: Class 1.
2. Adjustable resistance range: 0~9992 with a minimum step of 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. Insulation resistance between the metal parts of the circuit to the housing > 50M0. Shipping list:
