新课程下的高考为了对高中物理教学树立正确的导向性、考查学生的能力、科学公正的选拔人才,特别注重以生产生活中的实际问题为问题情境.电容器和电感作为电子电路不可缺少的电子元件,自然可以作为很好的实际问题情境.本文着重研究电容器和电感在直流电路中充放电的图像问题.一、电容器1.电容器的结构两个彼此靠近且绝缘的金属导体构成一个电容器,常见的
In order to set the right direction for physics teaching in high school, examine the ability of students and select talents with scientific fairness, paying special attention to the practical problems in production and life as the problem situation.Capacitors and inductors as an indispensable electronic circuit Components, naturally can be used as a good practical problem situation.This paper focuses on the capacitor and inductor in the DC circuit charge and discharge of the image problem.First, the capacitor structure of the capacitor two close to each other and the insulation of the metal conductor to form a capacitor, common of
