Resistance (resistance), we often call it R in daily life, the unit is ohm, if you want to define the resistance, it is the size of the resistance of the conductor to the current, the resistance is a current limiting element, the conductor’s current resistance If the blocking effect is large, we say that its resistance is large, otherwise, it is said that its resistance is small. But resistance will not disappear because there is no current flowing through the conductor. Resistance is an inherent property of a conductor. Even if there is no current flowing through the conductor, its resistance still exists.Today author from QiHe smt pick and place machine sharing you with the details .<\/p>\n\n\n\n

Classification of resistance<\/h3>\n\n\n\n

Resistance is just a general term. After a deep understanding of it, you will know that there are many kinds of resistance, which can be divided into:
Fixed resistors, variable resistors, special resistors, RT-type carbon film resistors, RJ-type metal film resistors, RX-type wirewound resistors, chip resistors, high-power resistors, and low-power resistors. Do you really know the various functions of resistors?<\/p>\n\n\n\n

Do you know the various functions of resistors?<\/h3>\n\n\n\n

partial pressure<\/h3>\n\n\n\n

When a resistor and another component such as a bulb are in series in a circuit, the current flowing through the resistor and the bulb is the same, and the sum of the voltages across the resistor and the bulb is equal to the total voltage across the resistor and the bulb as a whole. At this time, the resistor acts as a voltage divider.<\/p>\n\n\n\n

electric shunt<\/h3>\n\n\n\n

When a resistor and another component such as a bulb are connected in parallel in the circuit, the voltage across the resistor is the same as the voltage across the bulb, and the sum of the current flowing through the resistor and the current flowing through the bulb is equal to the total current flowing through the resistor and the bulb . At this time, the resistor acts as a shunt.<\/p>\n\n\n\n

impedance matching<\/h3>\n\n\n\n

Impedance matching refers to the process of using some methods to make the load impedance and the internal impedance of the excitation source adapt to each other in order to obtain a working state of maximum power output during the signal transmission process. And one of its methods is to realize by changing the impedance. In this case, the resistance plays the role of its impedance matching.<\/p>\n\n\n\n

filtering<\/h3>\n\n\n\n

In the charging and discharging circuit composed of a resistor and a capacitor in series, in this infinite cycle of charging and discharging, we call the role of the resistor as a filter.<\/p>\n\n\n\u9605\u8bfb\u66f4\u591a\uff1aWhat are the functions of a resistor?<\/span><\/a>\n\n\n
