Reverse polarity means connecting a power source, or polarised componenet, with the positive and negative poles the wrong way round. If the positive and negative supply is connected the wrong way round in electronic devices, it usually causes damage, because semiconductors are sensitive to polarity.f you reverse the polarity of the power supply, the rectifier is now in full conduction, across the supply, causing a dead short. This shunts any power away from the radio and blows the fuse in the line, thus protecting it.
The latter terms are more descriptive and will be used throughout this article. Polarity results from the fact that an electrical circuit has a negative and a positive pole. Direct current (DC) flows in one direction, resulting in a constant polarity.Alternating current (AC) flows half the time in one direction and half the time in the other, changing its polarity 120 times per second with 60-hertz current.he latter terms are more descriptive and will be used throughout this article.
