Series and parallel circuits
... All of the components in a series circuit are connected in a loop. If the loop or circuit is broken or any of the components fail, the circuit is incomplete and will not work. The same amount of current flows though each component equally. Both lamps will light to the same brightness. The energy giv ...

Circuit breaker
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.
