The naming rules for potentiometers are the same as the naming method for resistors, but they start with the letter W. Its marking method is to use the straight labeling method, and the type, nominal power, resistance, and the relationship between the resistance and the rotation angle are marked with letters and numbers on the potentiometer shell. The following article will tell you about the test of the potentiometer, whether it is good or bad, and what are its main parameters?

With the shortage of energy and the pressure of environmental protection in the world, large-capacity power batteries gradually form the main body of power sources. Among them, lithium batteries as green batteries, which will not cause secondary pollution and have no memory effect, have gradually become the market for power sources. Application first choice. power lithium batteries have the advantages of high energy, high battery voltage, wide operating temperature range, long storage life, high power endurance, low self-discharge rate, light weight, green environmental protection, and no memory effect. They are mainly used in hybrid power. Vehicles, electric vehicles, electric bicycles, and future solar LED street light energy storage equipment. The environmental adaptability, high specific energy, high safety and lightweight power lithium battery are becoming the research hotspot at home and abroad and the future development direction.
