Question

Quizplus · Accepted Answer

A current source is a device that maintains the same amount of current flowing through it regardless of the voltage across it. When you reduce a current source to zero, it means that no current is flowing through it anymore. Therefore, it is effectively replaced by an open circuit, which means that there is no connection or pathway for the current to flow through.
