摘要
针对文献[1]提出的关于理想运放"假短真断(虚短实断)"的说法,对"虚短虚断"概念进行了讨论,指出"假短真断(虚短实断)"的说法是不合理的。讨论了"虚短虚断"概念在教学中的注意点,包括"虚短"成立的条件、"虚地"概念以及运放输出电流的来源等。本文的讨论可供从事电路教学的教师参考。
This paper discusses the concept of ＂virtual short and virtual open＂ of ideal op-amp to clarify the unreasonable view of ＂false short and true open （ virtual short and real open）＂ which is proposed in [ 1 ]. Some concerns that should be paid attention to in teaching has been pointed, including the condition of ＂virtual short＂, the concept of ＂virtual ground＂ and the source of op-amp output current. The discussion is helpful in circuit teaching
