Reverse polarity is a situation through which the constructive and detrimental terminals of {an electrical} system are reversed. This could be a harmful state of affairs, as it might probably trigger harm to the system and/or private damage.
There are just a few other ways to examine for reverse polarity. A technique is to make use of a multimeter. Set the multimeter to the DC voltage setting and join the constructive result in the constructive terminal of the system and the detrimental result in the detrimental terminal. If the multimeter reads a detrimental voltage, then the polarity is reversed.
