欧姆表既是闭合电路欧姆定律的一个重要应用,又是常用万用表的一个主要组成部分,结合教材编写有关欧姆表的物理试题既可巩固学生对闭合电路欧姆定律的掌握和应用,又可提高学生对万用表欧姆挡的实际选用和操作能力.因此近几年的高考物理试题以及地方高考预选题反复出现有关欧姆表的题
Ohmmeter is not only an important application of the closed circuit Ohm’s law, but also a major part of the common multimeter. Combining the textbook with the physics questions on the ohmmeter can consolidate the students’ mastery and application of the closed circuit Ohm’s law and improve the students’ The practical selection and operation capability of the multimeter’s ohmic block. Therefore, in recent years, the college entrance examination physics questions and local college entrance examination pre-selection questions have repeatedly appeared ohmmeter questions.
