What word completes both blanks in the following statement: People can become part of a ___________. When a person becomes part of an electrical __________, that person can be shocked.

• A. circuit
• B. fuse
• C. conductor
• D. wire

Answer: (A)

The key idea is how electricity flows through a complete path. People can become part of a circuit by completing the electrical path between the power source and return. When a person becomes part of an electrical circuit, current can flow through the body, which can cause a shock. The term circuit is the standard way to describe that complete path for current.

A fuse is a protective device, not something a person becomes part of. A conductor describes a material that carries current, not a person joining it. A wire is a component that carries current, but you wouldn’t say a person becomes part of a wire.
