(E.g., negative ion mode in my case) Thank you so much for your help ... NettetFor beginners, the visualization of instantaneous polarity method is slightly weak and therefore not so simple and easy to use. The writer of the paper has refined the amendment of instantaneous polarity method through his teaching experience in an attempt to make the judgment of the nature of feedback easier and more convenient …

Leads of primary and secondary windings are said to be of the same polarity when instantaneous current entering the primary winding lead results in instantaneous current leaving the secondary winding lead as though the two leads were a continuous circuit. In the case of two windings wound around the same core in parallel, for example, the polarity will be the same on the same ends: A sudden (instantaneous) current in the first coil will induce a voltage opposing the sudde…
