Problem

A potential–position graph shows that as one moves from point X to point Y through a certain resistor, the potential drops linearly from 6 V to 2 V. Which statement about the conventional current in the resistor is most consistent with this observation? a) The current flows from Y toward X because charges move from low to high potential.\text{The current flows from Y toward X because charges move from low to high potential.} b) The current is zero because the potential drop is uniform.\text{The current is zero because the potential drop is uniform.} c) The current flows from X toward Y, from higher to lower potential across the resistor.\text{The current flows from X toward Y, from higher to lower potential across the resistor.} d) The potential–position graph alone is insufficient; the direction of current cannot be determined.\text{The potential–position graph alone is insufficient; the direction of current cannot be determined.}
