众所周知,在科学实验中,误差不可避免,只能减小。然而,在研究“串、并联电路电压特点”的实验中发现,不仅实验所得的数据与书上所给出的结论相悖,而且存在的误差十分之大。在惊讶之余,产生了这样的疑问:为何会存在这么大的误差?是什么原因造成的?对实验中所用的导线与开关是否是零电阻产生了疑问,对此展开了一系列的实验探究……
As we all know, in scientific experiments, the error is inevitable, can only be reduced. However, in the study of “string and parallel circuit voltage characteristics”, it was found that not only the experimentally obtained data are contrary to the conclusions given in the book, but also the errors are very large. Surprised, the question arises: Why is there such a big error? What causes? The question of whether the wires and switches used in the experiment are questionable of zero resistance, a series of experimental exploration ...
