Study Notes
- Electrical circuits have four parts: a source, light bulb, wires, and switch.
- In an open circuit, electricity does not flow, while in a closed circuit, it flows.
- Christmas lights have a series circuit, while lights at home have a parallel circuit.
- In a series circuit, when one bulb is busted, all other bulbs in the circuit will not light up.
- In a parallel circuit, each bulb has its own pathway, so when one is busted, the others still light up.
- Homes have a parallel circuit.
- Each light and electrical device in a parallel circuit has its own path of electricity.
- Turning off one device in a parallel circuit does not affect the others.
- A break in one pathway in a parallel circuit does not affect the other pathways.
- A series circuit is not appropriate for homes.
