1、恒定电流 恒定电流是高中物理电学的重点内容，占有很重要的地位。该部分知识可分为两大部分：第一部分以部分电路欧姆定律为中心，包括了六个基本物理量（电压、电流、电阻、电功、电功率、电热）、三条定律（部分电路欧姆定律、电阻定律和焦耳定律）、电路若干基本规律（串联、并联电路的规律）；第二部分以闭合电路欧姆定律为中心，讨论电动势概念，闭合电路中的电流，路端电压，以及闭合电路中能量的转化等。另外，本单元知识与学生实验结合紧密，因而往往通过实验考查该部分知识的运用情况。 本章及相关内容知识网络恒定电流闭和电路部分电路外电路欧姆定律ODINGL规律基本概念电源三条定律ODINGL焦耳定律、电功、电功率电源
