电学是初中物理教学的重要内容之一,涉及电流、电阻、电压、电功、电功率等基本概念的辨析;欧姆定律、焦耳定律等物理规律的理解和应用;串、并联电路的变化、电路故障的判断、电学与其它知识点、甚至与化学学科的联系等,历来列为中考的重点内容之一.本文选取几道电学考题,剖析这些试题所渗透的能力考查要求.
Electricity is one of the important contents of junior high school physics teaching. It involves the analysis of basic concepts such as current, resistance, voltage, electric power and electric power; the understanding and application of physical laws such as Ohm’s law and Joule’s law; changes in series and parallel circuits and circuit failures. The judging, electrical and other knowledge points, and even the links with the chemical sciences, etc., have historically been listed as one of the key contents of the entrance examination. This article selects several electrical examination questions and analyzes the examination requirements for the infiltration of these questions.
