Answers. Best Answer: Reverse polarity is the opposite of normal polarity. Normal polarity in electronics is when you have the positive hooked up to the positive terminal and the negative to the negative terminal.Reverse polarity would be having the positive hooked up to the negative terminal and the negative to the positive terminal.The same concept can be used with magnets.everse polarity would be having the positive hooked up to the negative terminal and the negative to the positive terminal. The same concept can be used with magnets.
Reverse polarity circuit example for output voltage is shown below. The polarity can be reversed by applying signal voltage. When the RS terminal is connected to AUX terminal, the output polarity is positive. Conversely, if RS terminal is connected to COM terminal, the output polarity is negative. Reverse polarity signal is designed as 24V (High).
