7. Electrical Circuits series circuit – the current has only one path; when one part of the circuit is broken, nothing will work ex) cheap Christmas lights

8. Series Circuit

9. Electrical Circuits parallel circuit – the current has separate branches to move through; when one part of the circuit is broken, the rest still works ex) household wiring

10. Parallel Circuit

11. Household Circuits In your home, parallel circuits branch out from the breaker box to the wall sockets. Each branch receives a standard 120 volts from the electric company.
