How many wires are typically present in household electrical wiring?

• A. Two
• B. Three
• C. Four
• D. Five

Answer: (B)

Household electrical wiring typically includes three wires: a live (or hot) wire, a neutral wire, and a ground wire. The live wire carries the electrical current to the outlet or fixture, while the neutral wire completes the circuit by carrying the current away from the device. The ground wire provides a safety mechanism, directing any stray electricity away from users and reducing the risk of electric shock. In most standard residential electrical systems, this three-wire configuration is designed to ensure both functionality and safety. The presence of these three wires allows for a complete circuit necessary for the safe operation of electrical appliances and fixtures in the home.
