学习了基本电路和安全用电知识后,我在想,图1所示的串联电路是最简单、最基本的电路,只有一个开关就可以控制用电器,能否用两个开关任意控制一个用电器呢?
After learning the basic circuit and the knowledge of safe use of electricity, I was thinking that the series circuit shown in Figure 1 is the simplest and most basic circuit. Only one switch can control the use of electrical appliances. Can we use either switch to control an arbitrary use? What about electrical appliances?
