When speaking of electrical circuits, what does the term "continuity" mean?
- A The circuit is rated for continuous operation
- B The circuit is a closed circuit
- C The circuit is designed for direct current (DC)
- D The circuit is supplied with backup power
Correct answer: B — The circuit is a closed circuit. From the official ISED question bank, verified word for word.
Why
Continuity simply means electricity can flow all the way through a path without any breaks, which is exactly what a closed circuit is. The full explanation — and one for every question — is in Pro.
