# Is it possible to loop power to make it run in a continuos loop? I know this isn't really useful, i was just wondering.

Lets say you had two power source and one device needing the power. Would you be able to have a switch and switch between the 2 power sources? My second question is, What if you had 1 Power Source and a switch. The switch is connected to the power source and a wire, and the output is the same wire connected, making a loop. Would power run in a continuos loop ? Or would you need a capacitor bank?

If you have a superconducting loop, you can have a large current circulate happily for years. They produce powerful magnetic fields, but need cooling with things like liquid helium.

Otherwise see kelseymh (a physicist)

whats a super conducting loop?

Think of a circle, or ring which has absolutely no electrical resistance - it's a "super"conductor. You can induce current to flow around it, which just keeps going because there's nothing to stop it. Though I agree with kelseymh on researching these things.

Google is your friend. So is Wikipedia. So is the dictionary sitting on your parent's bookshelf. If you want to learn new things, start by learning how to look things up for yourself. You'll stumble across stuff you didn't expect.

what if you hook A to B to Capacitor Bank to A

It's still a short. See Frollard's comment below. A closed loop won't circulate current any more than you can take a hose full of water, hook the ends together, and expect the water to magically go around and around and around...

What he's referring to (author) is a short circuit :D Author: Electricity needs a potential difference (voltage; i.e. 'reason to go from a to b') and a circuit to get there in order for there to be current flow. If you hook a to b and back to a, it wont go in a circle.
Regarding your second question, I think you are describing something that exists. A circuit that repeatedly switches (part of) itself off and on is called an oscillator. If it has only off/on and no in-between, that type is called a astable multivibrator.

Of course, as kelseymh pointed out, the power source will eventually run out, regardless of whether you do something useful with the circuit.
