Current will take which path to return to its source?

Current flows according to the principles of electricity and is influenced by the available paths. The correct answer indicates that current can take any and all paths available to return to its source. This phenomenon is rooted in the fundamental nature of an electrical circuit, where current will distribute itself among all available conductors based on the resistance offered by each path.

In real-world scenarios, while current prefers paths of least resistance due to Ohm's Law, it does not restrict itself to only one path or the shortest path. Instead, if multiple conductive paths exist, the current will divide itself based on the resistance of those paths. This means that all routes will be utilized, resulting in a situation where the total current supply spreads across various paths in the circuit.

This understanding is crucial for electrical work, as it affects how circuits function, including safety considerations, load balancing, and fault scenarios. Knowing that current can traverse multiple paths helps to design and analyze electrical systems appropriately.
