电路及元器件基本知识 1.电感元件 凡是应用电磁感应原理工作的元件统称电感元件。电感元件与电阻器、电容器一样,是电子电路中最常用的重要元件。常见的电感元件有一般电路中用的固定电感器、高频阻流圈、低频阻流圈,收音机和录音机中用的各种电感线圈,电视机上用的偏转线圈、振荡线圈和行线性调整线圈等等。它们在电路中虽然作用不尽相同,但都是利用电磁感应原理进行工作的。电感元件一般是由导线(大多为漆包线或其他绝缘表层导线)绕成空心线圈或带铁芯(磁芯)线圈而制成,所以通常也称作电感线圈,或简称为线圈。
Basic knowledge of circuits and components 1. Inductive components Any application of electromagnetic induction principle components commonly referred to as inductive components. Inductor components, like resistors and capacitors, are the most commonly used and important components in electronic circuits. Common inductors include fixed inductors, high-frequency choke coils, low-frequency choke coils, various inductors used in radios and voice recorders, deflection coils for television sets, oscillating coils, and linear adjustment coils and many more. Although their role in the circuit are not the same, but the principle of electromagnetic induction are used to work. Inductor components are usually made of wire (mostly enamelled wire or other insulated surface wire) wound into a hollow coil or core (core) coil made, it is also commonly referred to as the inductor, or simply coil.
