In a circuit with two parallel paths, the larger fraction of the current tends to follow the path that:

In a circuit with two parallel paths, the larger fraction of the current flows through the path that has lower resistance. This is a consequence of Ohm's Law, which states that current (I) is inversely proportional to resistance (R) when voltage (V) is kept constant, as per the formula I = V/R. Therefore, if one path has lower resistance, it allows more current to pass through compared to a path that has higher resistance.

In practical terms, this means that for any given voltage applied across the circuit, the path with lower resistance will present less opposition to the flow of current, thereby drawing a larger share of the total current available in the circuit. This concept is critical in understanding how current splits in parallel circuits, where the total current divides among available pathways based on their relative resistances.

The other options can be analyzed in context: a path with higher resistance would lessen the current flow through it, a larger voltage drop does not directly affect the current distribution in parallel paths, and the length of a path may affect resistance but does not determine the current fraction in the way resistance does. Ultimately, it is the resistance that primarily dictates how much current each path will carry.
