What is Resistor and How to Read Resistor Color Code
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？
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?
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?
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
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
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
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？
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?
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".
Resistor Basics: Resistor Symbol
The resistor symbol as a kind of identification is unique to each type of resistor. There are many types of resistors, which can be divided into fixed resistors, variable resistors, special resistors, high-power resistors, low-power resistors, etc.
