What does "circuit" mean? Can I also use this in daily conversation?

A "circuit" is a single complete, closed path that allows an electric current to flow, whereas a "circuit-breaker" is a device that allows the electricity flow to safely stop. If you speak about electric components frequently, you can use these terms in casual conversation. Ex: All electronic devices have circuits. Ex: The circuit-breaker shorted and caused a blackout.
