电学中的概念有很多、学习方法也不相同。其中,恒定电流和静电学中有两个重要的概念,即电阻和电容,初学的学生普遍反映有点难度,究其原因:其一,对概念本身理解不够;其二,对概念的应用不多。以下就这两个概念谈谈它们的联系及理解方法与应用,望给初学电学的学生一点帮助。 There are many concepts in electricity, learning methods are not the same. Among them, there are two important concepts in constant current and electrostatics, namely, resistance and capacitance. Beginners students generally reflect a bit of difficulty. The reason is as follows: First, the concept is not understood enough; secondly, the concept is not applied much . The following two concepts to talk about their contact and understanding of methods and applications, hope to begin with electrical students a little help.
