Resistor is an electronic component that has the function of partial voltage and shunt. It can not only change the voltage, but also the transformer. It can boost or lower the voltage, and the resistor can play the role of step-down. Power consumption is enormous. In recent years, transformers and resistors have developed rapidly, and transformers have advanced in the process of urbanization, and transformers have also ushered in a golden age. Since the 21st century, with the development of urbanization and the speed of const...

The fixed resistance means the resistance value does not change much under the influence of external conditions. Fixed resistors have a nominal resistance, which is usually marked on the resistor. In many devices, fixed resistors are used. A fixed resistor is connected to the coil of the PLC output. This fixed resistor is also called freewheeling resistor or a bleeder resistor. The current resistance is used to consume the self-induced electromotive force generated at the moment of power-off. The fixed resistor also acts as a...

There are usually many resistors in the circuit design. When the circuit design buffer, a resistor is usually added to the operational amplifier feedback path. Many junior engineers dont understand why a resistor is added here, but the design makes sense. In fact, the design of the resistor is very meaningful, which can stably improve the stability of the circuit, as shown below: In this circuit we can see a resistor. The resistors for this circuit are typically used in low-speed applications 50 MHz to eliminate the DC offset...

In the elevator equipment in our life, the motor equipment is usually used for the take-off and landing, and the brake resistor is inevitably used in this process. We know that the braking resistor is a carrier that consumes the regenerative energy of the motor in thermal energy. The braking resistors commonly used in elevator equipment are generally aluminum alloy resistors and ripple resistors. These two resistors have their own advantages and disadvantages in the elevator equipment, lets analyze it. We know that in the var...

Electric vehicles are widely sought after worldwide, and the battery management system using high-precision shunts is constantly evolving in technology, and is currently entering from cars, buses, and trucks. Since the form of energy consumption of electric vehicles has undergone a fundamental change, the ratio of energy supply network, energy supply time and form, and vehicle value is very different. These huge differences determine that electric vehicles must adopt a different business model than fuel vehicles. . At present...

Innovation is no longer a challenge. The real challenge is to learn how to use resistor technology in the right way. In the development of the LED market, the innovation of smart LED technology brings new market opportunities. With the rise of the smart home industry, more demands are placed on the networked control of LED lights. In the past, LED lights produced by using bluetooth or chips combined with precision resistors can realize the wireless control of LED color and brightness, Bluetooth. The tight combination of chips...

The voltage on the precision resistor is connected to the output voltage connector and the internal four-position AC/DC current meter. The gear selector on the precision current shunt panel selects one of the five gears and outputs it to a four-and-a-half-digit voltmeter, a four-and-a-half voltmeter measures more accurate AC or DC current values. For higher accuracy or resolution current displays, a five-and-a-half-digit or better meter can be used to connect to the output voltage connector. The precision current shunt has fi...

Plug-in resistors and chip resistors are two very important resistors. Both resistors are used in many applications, but it is not difficult to find that the shipments of these two resistors are quite different. Usually the use of plug-in resistors is several times the chip resistor. Why is this happening because of their price or because of their package mode? Let me analyze it carefully. In fact, engineers who have applied plug-in resistors are actually very simple. This is because of the packaging process of the plug-in re...
