reverse polarity
Swap positive negative
Reverse polarity describes a condition where electrical current flows opposite to its intended direction, typically because positive and negative connections are swapped.
In electronics, reverse polarity can damage equipment or prevent it from functioning: Check for reverse polarity before connecting the battery.
The phrase appears in science fiction as technobabble—a vague solution to impossible problems: Just reverse the polarity of the neutron flow.
