在各类试题中,电路的设计是常见题型.而在电路设计题目中常常会出现一些定值电阻,有的定值电阻阻值较大,有的电阻阻值较小,而学生对这些定值电阻的使用往往束手无策,这里给大家介绍几种在电学实验中常见的定 In a variety of questions, the circuit design is a common problem.And in the circuit design topics often appear some of the value of resistance, some of the value of the resistance of a larger resistance, and some smaller resistance, and the students of these The use of fixed value resistors are often at a loss what to do here to introduce several common in electrical experiments
