In a circuit where a copper thread and a rubber thread are connected in parallel to a battery, which path carries the current?

Explanation:
In a parallel circuit, current favors the path with lower resistance. Copper is a good conductor with low resistance, while rubber is an insulator with very high resistance. Because the rubber path offers so much resistance, almost no current flows through it. The battery voltage is the same across both paths, so most or all of the current goes through the copper thread. Therefore, the copper thread carries the current.
