摘　　要：电学实验中，很多试题会考查实验电路设计、实验器材的选取，这也是高考考查的重点．在电路设计、实验器材的选取中往往会涉及保护电阻的选取与运用，学生对此感觉很难而无从着手，保护电阻的选取与运用需要详尽地分析和考量．Many questions will examine the design of experiment circuit and the selection of experimental equipment in the college entrance examination. The protective resistance is often involved in the design of experiment circuit and the selection of experimental equipment. The selection and application of the protective resistance is difficult to the students. The selection and application of protective resistance should be analyzed and considered very carefully.

关 键 词：电路设计 分压电路 保护电阻 测量精度 位置
