Hi PhysicsForums,
Why would a parallel circuit(or in blood) decrease resistance?
Here is my thought experiment and where I got stuck:
Say from aorta to one arteriole, the resistance is super high on that flow(this big amount of flow is entering a tinier area), but add more arterioles and we have a bigger area in total and blood can flow better(but whyyyy) Why would having a greater area conceptually help with the resistance?
