一、根据串联、并联电路的定义识别串联的用电器,在电路中是逐个顺次连接的,它的特征是“一串”,我们把用电器等效地画到一条直线上看,就像是一串“糖葫芦”,如图1中的L1、L2;并联的用电器,在电路中是并列连接的,它的特征是“并列”,有并在一起的意思,好像用电器接在用导线围成 First, according to the definition of serial and parallel circuits, identify the series of electrical appliances, which are connected one by one in the circuit. Its characteristic is “a string”. We draw the electrical appliances equivalently to a straight line, just like Is a series of “candied fruit”, as shown in Figure 1, L1, L2; parallel electrical appliances, in the circuit is connected in parallel, it is characterized by “side-by-side”, with the meaning of together, it seems to use electrical appliances to use Wire surrounded
