What are Braking Resistors?
Cranes, lifts, elevators, turbines and electric vehicles including trains that use motors, require accurate and precise speed control. To achieve accurate speed control, it is important to have both control acceleration and deceleration, that is braking. Today, we are going to talk about braking resistors.
How to Use Resistors and Apply Ohm's Law in Electrical Circuits
Understanding how to utilize resistors and apply Ohm's law is a fundamental part of electrical engineering and is required for anybody interested in building and designing electrical circuits. We will look at the fundamentals of resistors, how they operate, and how to apply Ohm's law to calculate resistance, current, and voltage in electrical circuits.
How to Measure Resistance and How to Detect Resistance?
There are many ways to measure resistance: ohmmeter, volt-ampere, volt-volt, ampere-ampere, bridge, substitution, comparison, half-deviation and so on. No matter what the method is, the experimental principle is no more than partial circuit Ohm's law and closed circuit Ohm's law as well as the basic law of series and parallel circuits.
Metal Oxide Varistor (MOV) Overview: Working and Application
The blue or orange-colored circular part that you can typically spot on the AC input side of any Power Supply Circuit is a Metal Oxide Varistor or MOV.
The Difference between Carbon Film and Metal Film Resistors
Invented by Boykin in 1959, resistors are today commonly used in almost all electronic circuits. Resistors can be described as a device that resists the flow of current flowing through itself, back when the resistor size was very huge and the tolerance value reached as high as 10 percent when it was implemented.
Thermistor Introduction--?Temperature Sensitive Component
Thermistors are a type of sensitive component, which are divided into positive temperature coefficient thermistor (PTC) and negative temperature coefficient thermistor (NTC) according to the temperature coefficient.
What Is A Chip Fixed Resistor?
The electronic component body of the non-patch component can carry more production information, such as specifications, manufacturers, product serial numbers, and the like. The volume or size of the patch component is in millimeters.
Resistor Basics: Types of Resistors

Varistor Guide: Working, Function, Types, and Application
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
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 Drives Autonomous Vehicles?
The autonomous vehicle (AV) industry continues to evolve across many aspects: technologies, use cases, safety standards, safety legislation, and many others.
How to Test an AC Capacitor with a Multimeter
In our practical life and work, the vast majority of electrical equipment or household appliances, are using alternating current (AC), the power supply department grid to provide alternating current.
What is a Ground Fault Circuit Interrupter?
A ground fault circuit interrupter(GFCI) is an electrical device installed to protect against severe electric shocks. It can also reduce electrocutions, minimize electrical burns and shock injuries, and detect ground faults, and interrupts the flow of electric current.
What is SMA RF Connector
The SMA connector is an effective sub-miniature RF and microwave connector that has a screw fixing to provide reliable connectivity.
