What Are the Functions and Applications of the Varistor?Page Browsing:9730
IntroductionVaristor, a resistive device with non-linear volt-ampere characteristics, which is mainly used to clamp a voltage and absorb excess current to protect the sensitive devices when the circuit is under overvoltage. Its English name is "Voltage Dependent Resistor" abbreviated as "VDR". Its resistor material is semiconductor, so it is a kind of semico...

How to Test Ground Resistance?Page Browsing:6060
IntroductionThe ground resistance is a resistance that the current flows into the ground from the grounding device and then flows through the earth to another grounding body or diffuses far away. The value of ground resistance reflects the good degree of contact between electrical device and the ground and reflects the scale of grounding grid.This article mainly introduces how to test the ground r...

What is the giant magnetoresistance (GMR)?Page Browsing:11882
IntroductionThe Giant Magnetoresistance (GMR) refers to the phenomenon in which the electrical resistivity of a magnetic material changes greatly when it has an external magnetic field as compared with the absence of an external magnetic field.It is a quantum mechanical effect that results from a layered magnetic thin film structure. This structure is formed by alternately laminating thin layers o...

The Pull-up Resistor and Pull-down ResistorPage Browsing:6402
IntroductionThe most basic function of pull-up or pull-down resistors (collectively referred to as "pull resistors") is to clamp a signal line with an uncertain state to a high level (pull-up) or a low level (pull-down) through a resistor. Regardless of its specific usage, this basic function is the same. But in different application, the resistance value will be different, whi...

The Functions and Applications of ResistorsPage Browsing:6216
IntroductionMany objects in our daily life are related to resistors, but some are very large and some are very small. The resistor we are talking about here is a resistor in an electronic device, but the resistor is often referred to as a resistor. Resistor is almost an indispensable part of any electronic circuit. As the name implies, the role of the resistor is to block the action of e...
