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.
A silicon pân junction in reverse bias. Connecting the p-type region to the negative terminal of the battery and the n-type region to the positive terminal corresponds to reverse bias. If a diode is reverse-biased, the voltage at the cathode is comparatively higher than the anode.he electrons that cross the pân junction into the p-type material (or holes that cross into the n-type material) will diffuse in the near-neutral region. Therefore, the amount of minority diffusion in the near-neutral zones determines the amount of current that may flow through the diode.
