The Water Circuit Analogy

Oh, too bad. That was not the correct answer.

Water always takes the way with the lowest resistance. The water in our circuit doesn't take the long way around, through the red water wheel; however, it simply flows past it. The result is that the red water wheel doesn't move!
But the water cannot flow past the black water wheel on the right. It can only flow through it and that means this wheel turns.

Try to find the similarity to the bird sitting on the voltage line! What could this mean for the bird?

If you are able to find this similarity, then you will have practically solved the problem.
