与“电路”相关的试题是高考中常见题型,涉及考点有:欧姆定律、电阻定律、电源的电动势和内阻、直流电路的动态分析、含容电路、电路故障、自感电路、电磁感应的电路、含变压器电路、远距离输电等,题型涉及选择、填空、计算,难度中等.本文通过典型例题解读这些核心考点,希望对同学们的学习有所帮助.考点一、欧姆定律【考点研读】欧姆定律的适用范围:欧姆定律只适用于纯电阻导体的导电情况,如金属导电、液体导电,对非纯电阻导电,如含电动机、气体导电时,不再适用.另外,一些金属导电时,若 Test questions related to the “circuit” is a common college entrance examination questions, involving test sites are: Ohm’s Law, resistance law, the power of the emf and internal resistance, DC circuit dynamic analysis, including capacitance circuit, circuit fault, inductance circuit, Electromagnetic induction circuit, including the transformer circuit, long-distance transmission, the question involves choice, fill in the blank, calculation, difficulty in the middle.This article through the typical examples of interpretation of these core test sites, hoping to help students learn. [Test site study] Ohm’s law of the scope of application: Ohm’s law is only applicable to the conductive state of pure resistance conductor, such as metal conductive, liquid conductive, conductive on non-pure resistance, such as with motor, gas conductive, no longer apply. Metal conductive, if
