When current is returning to the source in an AC circuit, it will take which of the following paths?

In an AC circuit, when current is returning to the source, it will take all conductive paths available. This phenomenon is based on the principles of electric current flow, particularly the behavior of alternating currents. AC is characterized by its oscillating nature, which means that current flows in both directions, and it will utilize every available conductive path to return to the source.

The concept of the current taking all conductive paths emphasizes the fact that electricity seeks to complete a circuit, and it will distribute itself among all paths in proportion to their resistance. Thus, even in a complex circuit where multiple paths exist, the total current divides among them based on the resistance of each path, but all paths will conduct some degree of current as long as they are connected and conductive.

Understanding this principle is critical for ensuring proper grounding and bonding in electrical systems to maintain safety and performance. In contrast, the other options imply a restrictive approach to how current behaves, which does not accurately reflect the nature of AC circuits.
