There are a wide range of types of resistors, and with the development of electronic technology, new types of resistors will continue to increase.

Varistor Guide: Working, Function, Types, and Application

Blog Apr 19, 2021

Varistor is an ideal protective element with the characteristics of high price, small volume, wide working voltage range, fast response to overvoltage pulse, strong resistance to impulse current, low leakage current (less than a few microamperes to tens of microamperes), small resistance temperature coefficient and so on.

What is Resistor and How to Read Resistor Color Code

Blog Feb 5, 2021

This paper shows the comprehensive introduction of resistor which is one of the common electronic components. Resistance is the ability to impede the flow of electrons, that is, the value of resistance, the unit is "Ω". A resistor is a device that has a certain resistance to current flow.

What Is Thermistor and How Does It Works？

Blog Sep 4, 2020

The thermistor is a semiconductor ceramic component made of transition metal oxide as the main raw material. It belongs to the category of negative temperature coefficient thermistor, and it has the characteristic that the resistance value changes with the change of temperature, that is, the resistance value. The temperature rises and falls.

How To Measure Ground Resistance?

Blog Aug 19, 2020

Ground resistance testing methods are usually the following: two-line method, three-line method, four-line method, single-clamp method and double-clamp method.

What Is the Insulation Resistance Meter and How to Test It?

Blog Aug 1, 2020

The insulation resistance meter is a special instrument for measuring the maximum resistance value, insulation resistance, absorption ratio and polarization index.

Resistance Classification and Its Parameters

Blog Jul 8, 2020

A resistor is a current-limiting component. After the resistor is connected to the circuit, the resistance of the resistor is fixed. Generally, it has two pins, which can limit the current through the branch connected to it.

Resistor Basics: Resistors in Series and Parallel

Blog Jun 19, 2020

Resistors are usually connected in a circuit in various ways, and the two most basic ways are series and parallel. This article will mainly introduce these two connection methods, including their definitions, formulas, circuit diagrams, examples and identification methods.

Photoresistor: Basics and Arduino Tutorial

Blog May 19, 2020

Photoresistor or light-dependent resistor (abbreviated as LDR) or photoconductor is a special resistor made of semiconductor materials such as cadmium sulfide or cadmium selenide.

What is the Current Limiting Resistor and Its Function？

Blog May 2, 2020

In a circuit, a resistor in series with other components and no signal output at its series connection, so that when the component connected in series is short-circuited, and the voltage applied to the resistor does not burn the resistor, such a resistor is a current limiter. Resistance, otherwise it is not called current limiting resistor, but called protection resistor, or load resistor.

Variable Resistor: Basics, Application Circuits＆Common Malfunctions

A resistor is a current-limiting element. After the resistor is connected to the circuit, the resistance of the resistor is fixed. It generally has two pins, which can limit the current flowing through the branch connected to it.

What is Resistor and Its Function?

Blog Dec 31, 2019

Before we understand resistors, we need to know what a resistor is. The resistance is often abbreviated as R, which is a basic property of a conductor and is related to the size, material, and temperature of the conductor. The basic unit of resistance is ohms, which is represented by the Greek letter "Ω".
