在学习过程中,含有电动机等非纯电阻电路是电学部分学习的难点,很多学生对概念混淆不清,思路不明确,导致求解错误。正确分析识别纯电阻与非纯电阻电路,是解决含电动机类电路问题的关键,也是分析问题能力与解决问题能力的重要体现。而实验探究的感性认识与具体事例的分析,可以帮助学生更深入地了解和分析解决电路中出现的各种问题。
During the learning process, non-pure resistance circuits such as motors are difficult to learn in the electrical part. Many students confuse concepts and have unclear ideas, leading to errors in solution. Correctly analyzing and identifying the pure resistance and the non-pure resistance circuit is the key to solving the problem of the circuit with the motor type, and also an important embodiment of analyzing the problem ability and solving the problem ability. The experimental understanding of the perceptual knowledge and specific examples of analysis, can help students better understand and analyze the various problems that arise in the circuit.
