In a parallel circuit, more electrical current flows through the branch with what type of resistance?

Highest
Lowest
Equal
None of the above

The correct answer is: Lowest

In a parallel circuit, more electrical current flows through the branch with the lowest resistance. This is due to Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R), or I = V/R. In a parallel configuration, the voltage across all branches is the same. When resistance is lower in one branch compared to others, the current flowing through that branch becomes higher since the lower the resistance, the greater the current for the same voltage. The other branches with higher resistance will have comparatively less current flowing through them because the proportion of voltage across each branch remains unchanged, while the lower resistance allows for increased current flow. This fundamental principle explains why in parallel circuits, components or branches with lower resistance dominate the current flow.
