... Summary: Advanced Connections Questions 1. Many flashlights use two D-cells. Are the D-cells used in series or in parallel with the light bulb? Why? a. Flashlights use series circuits because voltage adds, so series D-cells provides more current, thus more light. 2. Would you recommend wiring string ...

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.
