一、电路设计与图表分析能力相联例1 (2005贵阳市)我们已进行过“科学探究;欧姆定律”。(1)请你在下边方框画出该实验的电路图(2)①由于电路中电流的大小受多种因素的影响,所以我们在探究某一因素变化对电流的影响时,必须保持其他因素不变,即采用了___法。②图1是某实验小组在探究过程 First, circuit design and chart analysis capabilities associated with Example 1 (2005 Guiyang City) we have conducted “scientific inquiry; Ohm’s law”. (1) Please draw the circuit diagram of the experiment in the box below. (2) 1 Since the magnitude of the current in the circuit is affected by many factors, we must maintain other factors in exploring the influence of a certain factor change on the current. No change, that is, using the ___ method. 2 Figure 1 is an experimental group during the inquiry process
