In a circuit, current prefers to flow through paths with lower resistance according to Ohm's Law (I = V/R). However, if there are multiple parallel paths, the current will split, and the path with the highest resistance will have the least current flowing through it. Therefore, while current does not travel along the path with the highest resistance, it will still exist in that path, albeit in a minimal amount compared to lower-resistance paths.

In a parallel circuit, the voltage across each load remains the same and is equal to the source voltage. The total current is the sum of the currents through each parallel branch, meaning that individual load currents can vary depending on their resistance. The overall resistance of the circuit decreases as more loads are added, following the formula ( \frac{1}{R_{total}} = \frac{1}{R_1} + \frac{1}{R_2} + \ldots + \frac{1}{R_n} ). This allows for multiple loads to operate independently, with each load receiving the full voltage from the power source.
