自动控制在我们的生活中已非常普遍,而自动化的实现离不开各种各样的电阻。接下来,华老师将针对实现自动控制常用的几种电阻结合例题进行讲解,希望能帮助同学们了解不同电阻的特性,在考场上碰到它们时能沉着应对。光敏电阻器又称光导管,特性是在特定光的照射下,其阻值迅速减小,可用于检测可见光。光敏电阻器是利用半导体的光电效应制成的一种电阻值随入射光的强弱而改变的电阻器,它对光线十分敏感,它的电阻值能随着外界光照强弱(明暗)变化而变化。它在无光
Automation is very common in our life, and automation can not be achieved without a wide range of resistors. Next, Mr. Hua will explain several commonly used resistance combination examples for automatic control, hoping to help students understand the characteristics of different resistances and deal with them calmly when they encounter them in the examination room. Photoresistor, also known as light pipe, is characterized by a specific light irradiation, the rapid decrease of its resistance can be used to detect visible light. Photoresistor is the use of semiconductor photoelectric effect made of a resistance value with the intensity of incident light changes in the resistor, it is very sensitive to light, and its resistance value with the external light intensity (light and shade) changes and Variety. It is dull
