一、问题提出近读《理想变压器空载时原线圈电流为零吗》的文章,读后教益颇深,作者运用当前的高中物理知识推出理想变压器在空载时原线圈的电流为零的观点.但笔者却不敢苟同.其实问题正误判别非常简单,只需一只变压器,一个交流电表通过实验即可.笔者做了这个简单的实验,发现空载时原线圈中是有电流的;而且,没有电流说在逻辑上也很难自圆其说,假 First, the question raised recently read the article “Is the ideal transformer zero current when the original coil is empty?”, after reading a lot of lessons learned, the author uses the current knowledge of high school physics to introduce the ideal transformer in the no-load primary coil current zero view But the author did not dare to agree. In fact, the problem is very simple to judge correctly, just a transformer, an AC meter through the experiment can be. The author did this simple experiment, found that the original coil is current when no load; and , there is no current that is logically difficult to justify, fake
