at 0:38 sec , I hear this statement and am confused:
"If we swap which ends of our wire are connected to the battery positive and negative, the current will flow through the wire in the other direction."
I would think the current still flows in the same direction (from positive to negative in the "conventional" way of describing it)
Wire end A to positive, wire end B to negative, current flow* from A to B.
Wire end B to positive, wire end A to negative, current flow from B to A.
Still positive to negative at battery, but moving in opposite direction in wire.
*Convention, ignoring electron direction, hole theory, or whatever.
