[Load Box Solution]How do resistors work and operate?2021-02-24 09:43: You have many projects that require the use of various strength resistors in circuits, so you may want to know about the function, working principle, and what happens if they are left outside. Let's start with some vocabulary: electricity is the flow of electrons, which are particles with negative charge. Voltage is the difference in charge between two points in a circuit. Voltage is also the force of current. Current measures the speed of electron flow. One simple way to understand the difference between voltage and current is to consider the water flowing out of a hose connected to the bottom of a tank. Here, the role of water is similar to that of current. Voltage is the water pressure, and current is the speed of the water flow. Resistance measures the ability of a material to resist the flow of electrons through it. If the width of the bottom hose remains constant, then more water can be added to the tank to increase the water pressure (voltage) without increasing the speed of the water flow (current).; read（36） label：资讯

[Resistors To Solve]Common Troubleshooting Tips for Resistors Failure2021-02-24 09:42: Over time, the use of resistors may avoid some usage problems, such as the appearance of noise and looseness during use, as well as the phenomenon of pointer jumping. The problems that arise at different times are also different. This article introduces some handling skills for the common problems that arise in the use of resistors. (1) First, let's observe the appearance of the thermistor. The potentiometer or thermistor must have clear markings, the solder pads or leads without rust, the axis of rotation flexible, appropriate tightness, smooth operation with no mechanical noise and vibration. (2) The wires or leads of the potentiometer or thermistor should not be loose when gently shaken by hand. (3) Set the multimeter resistance switch to the appropriate setting and measure the resistance value of the potentiometer or thermistor. If the measured value is different from the marked value, the potentiometer or thermistor needs to be replaced.; read（28） label：资讯
