When using the resistor box, the two wiring columns are connected to the circuit (the two terminals do not distinguish between the positive and negative electrode), and the tubing can get the arbitrary resistance between 0 ~ ×××××× Euro (usually 9999.9 Euros)value.(Usually rotating the tray clockwise) The number of instructions corresponding to each spinning plate is multiplied by the multiple marked by the facade, and then added together, which is the resistance value of the access circuit.
Principles of resistors
The resistor box is a variable resistor that can regulate resistance and can show resistance values.Compared with the sliding resistor, the sliding resistor cannot indicate the resistance value of the connected circuit, but it can continuously change the resistance in the access circuit.The resistance box can indicate the resistance value in the connected circuit, but the resistance value changes are discontinuous.
The role of the resistor box
The role of the resistor box is that the resistance value of the access circuit can be arbitrarily changed, thereby changing the current and voltage of the circuit.
The advantages and disadvantages of the resistor box
The advantages can indicate the resistance value of the connected circuit and can gradually change the resistance of the connected circuit.When the current passs through the resistance component, the heat reaction will cause each material of the device to expand or shrink the mechanical changes.The same result can also produce the environmental temperature conditions.Therefore, the ideal resistance element should be able to balance themselves based on these natural phenomena, and maintain physical consistency during the resistance processing process. There is no need to perform thermal effect or stress effect compensation during use, thereby improving system stability.Disadvantages jumping changes resistance.Although the resistance of the resistor box is variable, it is not linear. It can only be a choice of one file and one file. In addition, the specific resistor box will have rated parameters, such as the rated voltage, the rated current, if the two exceeded that the two are beyond the result of the excess of the two, which causes the two to exceed the leading causeDamage. Stress (regardless of mechanical stress or thermal stress) can cause changes in resistive electrical parameters.When the shape, length, geometric structure, configuration or modular structure are affected by mechanical or other factors, the electrical parameters will change.
How to read the resistors
Reading method: The number of instructions corresponding to each spinning plate multiplied by the multiple marked by the panel, and then added together, that is, the resistance value of the access circuit.
