电学是初中物理的重点之一,在中考题中呈现题设条件隐蔽复杂,题型多变,综合性强的特点,因而难度上相对较大,往往给同学们无从下手的感觉。但这不用怕,只要我们在复习的过程中,循序渐进、见识宽泛、掌握方法,在对电学中各量的定量关系和适用范围熟练掌握的基础上,准确审题,定能从题目的叙述中找到相关的信息,正确选择合适的公式进行解答。下面老师例举一些题例,进行解题思路剖析,让同学们找到应对的办法:
Electricity is one of the focuses of physics in junior high school. In the middle school entrance examination, there are characteristics such as concealed and complex conditions, changing subject types and strong comprehensiveness. Therefore, the difficulty is relatively large, which often gives the students no sense of starting. But do not be afraid, as long as we review the process, step by step, broad knowledge, master the method, in the quantitative relationship between electrical quantities and the application of proficiency, based on accurate examines, will be able to find the title narrative Relevant information, correct choice of the appropriate formula to answer. Here are some examples of teachers to explain the problem-solving ideas, so that students find ways to deal with:
