1.电容(器)是储存电荷(压)的容器:顾名思义,它是一种储存电荷的“容器”(简称“电容”)。尽管电容器的品种繁多,但它们的基本结构都是由两片相距很近的金属极板和中间绝缘介质组成的。当电容器接入到直流电源电路时,将发生电源的正极从与它相连的极板上吸引电子,电源的负极将电子推斥到与它相连 1. Capacitor (container) is the storage charge (pressure): as the name suggests, it is a charge storage “container” (referred to as “capacitor”). Despite the wide variety of capacitors, their basic structure consists of two closely spaced metal plates and an intermediate dielectric. When the capacitor is connected to the DC power circuit, the positive pole of the power source will attract electrons from the plate to which it is connected, and the negative pole of the power source will repulse the electrons to it
