Parallel Circuits

Each bulb is attached to the circuit and to the power source. There are two loops. If one goes out, the rest can stay on. All houses and buildings are wired on parallel circuits so we can be in other rooms without having all the lights on at the same time.
Series Circuits

Each resistor is attached to the power source on a single loop. If one bulb goes out then all the bulbs go out.
