Electricity follows the path of ___ resistance.

• A. Greatest
• B. Zero
• C. Least
• D. Moderate

Answer: (C)

Electric current follows the path of least resistance. With a given voltage, current is inversely related to resistance, so it flows more easily through the route that offers the smallest opposition. In circuits with multiple parallel paths, the current divides so that more of it goes through the lower-resistance path, meaning the path with the least resistance carries the most current. A path with zero resistance would imply infinite current, which isn’t possible in real wires, so that option isn’t realized in practice. The other choices would imply more current through higher or moderate resistance, which doesn’t match how current distributes.
