The role of alloy resistance and its application in circuits

Introduction

Resistors are common electronic components in our daily lives, playing important roles in circuits such as voltage division, current limiting, and current regulation. With the development of technology, people's demand for resistors is increasing. In order to meet this demand, scientists have developed many different types of resistors, among which alloy resistors have attracted much attention due to their excellent performance and wide applications. This article will provide a detailed introduction to the role of alloy resistors and their applications in circuits

1、 The role of alloy resistance

1 Partial pressure effect

One of the main functions of alloy resistance is to divide the voltage. In an AC circuit, as voltage varies over time, a component is needed to limit the magnitude of the current and enable other components in the circuit to function properly. At this point, the alloy resistor plays a voltage divider role, adjusting the voltage distribution in the circuit by changing the resistance value

2 Current limiting effect

In addition to voltage sharing, alloy resistance can also play a role in limiting current. When the total current in the circuit is too high, in order to protect other components in the circuit from damage, a current limiting element is needed to limit the magnitude of the current. At this point, the alloy resistance can play a current limiting role by changing the resistance value to control the magnitude of the current

3 Adjusting the current effect

Alloy resistors can also be used to regulate current. In certain specific application scenarios, we need to precisely adjust the current in the circuit. At this point, the alloy resistance can be changed as needed to effectively control the current

2、 The application of alloy resistors in circuits

1 Power filter

In power filters, alloy resistors are mainly used to reduce the ripple coefficient of the output voltage. Due to the large fluctuations in the output voltage of the power supply, it is necessary to use filters to denoise it. At this point, the alloy resistor can adjust the on state distribution of the circuit by changing its resistance value, effectively reducing the ripple coefficient of the output voltage

2 Electric motor drive

In the electric motor drive system, alloy resistors are mainly responsible for limiting the starting and operating currents of the motor. When the motor starts, a larger starting current is required to overcome inertial forces; During the operation of the electric motor, due to changes in load, the current also needs to change accordingly. At this point, the alloy resistor can control the starting and operating currents of the motor by changing its resistance value, ensuring the normal operation of the motor

3 Internal power management of computers

In internal power management of computers, alloy resistors are mainly used to regulate the power supply voltage of CPUs and other hardware modules. Due to the different voltage requirements of different modules, it is necessary to use alloy resistors with different resistance values to adjust the power supply voltage. This can ensure the normal operation of each module and effectively save energy and reduce emissions

Summary

Alloy resistors, as an important electronic component, have various functions such as voltage divider, current limiting, and current regulation. In practical applications, alloy resistors are widely used in power filters, motor drives, computer internal power management, and other fields, bringing convenience to our daily lives. With the continuous development of technology, the application prospects of alloy resistors in the future will be even broader
