电路里零件全有元件有器件前面讲过,电路主要由电源、导线、负载这三个主要部分组成。在实际电路中,除了上述这三部分外,还需要有更多的电子元器件,才能组成一个完整的电路。各种电子机器或器具,如收音机、电视机等都是由许多不同功能的元器件组成的。按其结构和性能不同,习惯上又分为电子元件和电子器件。例如电阻器、电容器等都叫电子元件;电子管、晶体管、变压器、扬声器、 Parts of the circuit has all the components There are components mentioned earlier, the circuit mainly by the power, wire, load the three main components. In the actual circuit, in addition to the above three parts, but also need more electronic components in order to form a complete circuit. A variety of electronic machines or appliances, such as radios and televisions, are made up of many different components. According to its structure and performance of different habits are divided into electronic components and electronic devices. For example, resistors, capacitors and other electronic components are called; tubes, transistors, transformers, speakers,
