In our circuit, current flows in the blue path and the red path. Sometimes people say things like, "the current takes the path of least resistance" but this is clearly not true since the red path has more resistance than the blue. Can you explain why all the current does not just the blue path (the least resistance path)? Think conceptually and come up with a metaphor for this situation.
