正确地解题是学好电工基础的重要环节,解题可以复习、巩固所学的知识,加深对电工基本概念和基本原理及基本分析计算方法的理解,培养分析问题和解决问题的能力。一题多解,解法的繁简,不仅取决于题目本身,还取决于解法的选择。一个很难的题目,当解法选择合理时,可能变得很容易,反之,可能变得很繁琐。有的题目需认真审题,确定出所要求的物理量,然后根据物理规律,寻找关系。因此,动笔解题之前,一定要克服思维定势,开阔解题思路,根据题型选择方法解答,可达到事半功倍的效果。本文结合电工习题的解答探讨这个问题。 Correct problem solving is to learn an important part of the basis of electrician, problem solving can review, consolidate the knowledge learned, deepen the basic concepts and basic principles of electrician and basic analytical methods of understanding, training and analysis of the problem-solving ability. More than one solution, the solution of the complex, not only depends on the subject itself, but also depends on the choice of solution. A difficult topic, when the solution is reasonable, may become easy, on the contrary, it may become very complicated. Some questions should be carefully examined, determine the required physical quantity, and then search for the relationship according to the laws of physics. Therefore, before moving to solve the problem, we must overcome the tendency of mindset, broaden the way of solving problems and answer them according to the questioning method, so as to achieve a multiplier effect. This article discusses the problem with the solution of the electrician exercises.
