Multiple Choice

The orientation that determines the direction of electron flow is called what?

Polarity is the orientation that defines which side is positive and which is negative, creating the potential difference that drives electrons. This arrangement sets the direction electrons prefer to move—typically from the negative side toward the positive side. If the polarity is flipped, the direction of electron flow would reverse. Voltage provides the driving force magnitude, current is the actual flow, and resistance opposes that flow; none of these alone specify which way the electrons travel.
