In the video, a melting and burning wire is illustrated, presumably due to current flow. A fuse is also illustrated as getting hot and then melting opening, presumably due to current flow. The commentator is not explicit in his explanation as to why the wire and fuse melted. Judging from the illustrations made, what must be a byproduct of current flow? Group of answer choices Light, especially when the conductor or load is undersized for the current flow Light, especially when the conductor or load is oversized for the current flow Heat, especially when the conductor or load is undersized for the current flow Heat, especially when the conductor or load is oversized for the current flow
