Rope loops Parallel circuits have junctions. They have more than one loop. We can use the rope analogy for parallel circuits. The teacher is very busy, she has two loops. Some of the children hold one loop and some two. Arthur The dogs are counting the ribbons that go past every second. Dog B is only watching his nearest rope. How many ribbons will he count each second compared with dog A? How will dog C's count compare with dog A's?
