In a circuit, the current requirements of some components are limited, and if the current exceeds its rating, it may cause the component to overheat, burn out, or deteriorate performance. The role of the current limiting resistance is to ensure that the components in the circuit work within a safe range by adjusting the size of the current.

Passive components such as resistors, capacitors and inductors play a vital role in the Printed Circuit Board (PCB). This article will explore the importance of these components, called passive components, in board design and function. First, we will understand the basic principles and functions of each passive component. Resistors control the flow of current, capacitors store and release charge, and inductors generate magnetic fields.

The detection of sensor quality mainly includes the basic characteristic detection technology and reliability test technology of the sensor. Converting all kinds of information into electricity is the basic characteristic of sensor. The method to describe the basic characteristics of the sensor includes mathematical model and basic characteristics index, which can be divided into static characteristics and dynamic characteristics according to the input of the sensor

A weight sensor, also known as a load sensor or force sensor, is a device used to measure the weight or force applied to it. It converts mechanical forces into electrical signals that can be interpreted and measured by a computer or control system.

When identifying the positive and negative polarity of a Zener diode, there are several key indicator criteria to refer to. First, notice the mark or logo on the diode. Usually, the positive terminal is marked as a line segment with an arrow or other special symbol, while the negative terminal is not marked at all. Second, look at the diode package. In most cases, the end with the longer pin is positive, while the end with the shorter pin is negative.
