初中物理电学计算是整个初中物理知识的一个重点,也是中考考查的难点内容.综观近几年各省市中考试卷,不难发现,电学计算大题以前纯理论的电路计算已慢慢淡化,现在更注重生活、贴近生活,运用物理知识解决实际问题.常以下面几类居多. Junior high school physical computing is a key point in the overall knowledge of junior middle school physics, and it is also a difficult part of the examination. Looking at the examination papers of various provinces and cities in recent years, it is not difficult to find that the circuit calculation of the pure theoretical theory has slowly faded before the major problems of electrical calculation. Pay attention to life, close to life, use physical knowledge to solve practical problems, often in the following categories.
