Learning about electrons starts with resistance

Resistance is a special electronic component used to limit or regulate the current of a circuit. Its function is mainly an electronic component in the circuit, and can be used to limit the current at a certain level, in order to achieve the control of the circuit.

Resistance is the most common electronic component, it can be modular, can be integrated on the chip, it has a wide range of industry applications. Resistance works by converting current into heat. This is APEM-B12LS. The resistance has two terminals connected to each other, when the voltage is applied, with a certain value of resistance of the current through the resistance, due to the thermoelectric effect of the resistance, with the increase of the current, the resistance of the surface temperature will occur, and the current value of the resistance is constantly changing by the resistance of the resistance. At the same time, when the current changes, the resistance value will also change, so we can adjust the resistance parameters by adjusting the current.

There are many kinds of resistors. One of them is called Fixed Resistor, which has a fixed resistor and can be used to control the current of the circuit so that the current value is stable and prevent recurrent phenomenon.

The other, called a Potentiometer Resistor, which changes the size of the resistance and thus the current by adjusting an internal potentiometer, is commonly used for volume and adjustment control.

In addition, there are several special resistors, including Capacitor Resistor, Feedback Resistor, Oscillator Resistor, etc.

Resistance has an important application in electronics, mainly used to control the current of the circuit, in the circuit design, resistance is also an indispensable component, must consider the elements, it can control the size of the current, different resistance has different resistance values, can effectively control the current of the circuit.

Nature of resistance

The formula for calculating resistance

A detailed classification of resistors

The volatility characteristics of resistance

The essence of resistance is to convert current into heat energy, so that the current produces thermal effect and is limited.

The formula for calculating resistance can be written as: resistance (R) = voltage (V)/current (I). detailed classifications of resistors include: Fixed Resistor, Potentiometer Resistor, Capacitor Resistor, Feedback Resistor, and Oscillator Resistor), etc.

The volatility characteristic of the resistance means that when the voltage of the resistance is constant, the current of the resistance will not change, this is because the resistance of the resistance is like a valve, the larger the resistance value, the larger the valve, the slower the current, and the smaller the resistance value, the smaller the valve, the faster the current. In addition, when the current of the resistance changes, the voltage of the resistance also changes, that is, the volatility curve of the resistance.

Characteristics and applications of resistance

The characteristics of resistance mainly include its resistance value, resistance thermal effect, volatility characteristics, the influence on lead resistance and so on. Resistance has a wide range of applications, mainly used to control the size of the current in the circuit, to prevent the occurrence of overcurrent phenomenon, but also used to change the size of the power in the circuit, such as changing the volume, signal strength and so on. In addition, resistance can be used to control the accuracy of the sensor, for example to convert a small change into a large change that can be measured.
