电容器属于电学的一个基本器件,有关电容器的问题因与电场、粒子的运动、恒定电流及力学知识相联系,能较好的考查学生灵活运用知识综合分析和解决问题的能力,因此在高考中频频出现,与电容有关的热点问题有以下四个方面:1 平行板电容器的两类问题的处理(1)电容器充电后断开
Capacitor belongs to a basic device of electricity. The problem concerning the capacitor is related to the electric field, particle motion, constant current, and mechanical knowledge. It can better examine the students’ ability to use knowledge comprehensively to analyze and solve problems. Therefore, it is frequently used in college entrance examinations. The emergence of capacitive-related hot spots has the following four aspects: 1 Handling of two types of problems with parallel-plate capacitors (1) Disconnection after charging capacitors
