Question

question 14 of 25 why is it important to have a closed circuit? a. it increases the resistance in the circuit. b. it allows an electric current in the circuit. c. it prevents a circuit from working. d. it prevents components from overheating.

Explanation:

A closed - circuit provides a complete path for electric charges to flow, enabling an electric current to exist. Resistance is determined by the components and materials in the circuit, not by whether it's open or closed. An open circuit prevents a circuit from working, not a closed one. And while proper circuit design can prevent overheating, the main function of a closed circuit is to allow current flow.

Answer:

B. It allows an electric current in the circuit.
