Intermittent electrical circuits are defined as circuits in which current flows for less than 2 minutes.

• A. True
• B. False
• C. Not applicable
• D. Cannot determine

Answer: (A)

Intermittent in this context means the circuit does not stay energized continuously; it conducts current only for a short period and then stops. The definition used here sets a threshold: if current flows for less than 2 minutes, the circuit is considered intermittent. That makes the statement true because it matches the course’s time-based criterion.

In practice, intermittent faults are tricky because they appear only briefly, often due to loose connections, worn or corroded contacts, or conditions like vibration or temperature changes that cause a circuit to open and close momentarily. When troubleshooting, you’d inspect connectors, check for loose or damaged wiring, and test under operating conditions to see if the fault repeats.

The other options don’t fit because the material defines intermittent specifically with this time criterion; there’s no need to say not applicable or cannot determine given the explicit definition.
