In a conductor, current always flows from which potential?

Current flow in a conductor is conventionally described as moving from higher potential to lower potential. This means that in a typical circuit, positive charges are considered to flow from the positive terminal to the negative terminal, establishing the direction of conventional current.

While the actual charge carriers in most conductors, such as metals, are electrons, which flow from the negative terminal to the positive terminal (hence the correct understanding aligns with the statement that current flows from negative to positive), it is important to note that in electrical engineering and most educational contexts, current is treated as flowing from the positive side to the negative side.

Therefore, while there is some ambiguity in the terminology used, the correct answer reflects the widely accepted convention which assumes current—defined in this conventional sense—flows from the negative terminal to the positive terminal, aligning with the behavior of electron movement inside the conductor.
