, What’s the difference between a series circuit and a parallel circuit?
✔✔In a series circuit, components are connected one after another, while in a parallel circuit,
components are connected across the same voltage source, allowing for multiple paths.
Why is grounding important in electrical wiring?
✔✔Grounding provides a safe path for excess electricity to flow into the earth, reducing the risk
of shock or fire.
What type of wire is commonly used for residential electrical wiring?
✔✔Non-metallic (NM) cable, often referred to as Romex, is commonly used for residential
wiring due to its flexibility and safety features.
How can you tell if a wire is live or not?
✔✔Using a non-contact voltage tester can help you identify if a wire is carrying electricity
without needing to touch it.
What is the function of a junction box in electrical wiring?
✔✔A junction box protects electrical connections and provides a safe space for wiring to branch
out, preventing accidental contact.
