In terms of continuity testing, what does it indicate if a reading approaches zero?

A reading that approaches zero during continuity testing indicates that the circuit is complete. In continuity testing, the goal is to check whether there is a complete path for current to flow. When the meter shows a reading close to zero, it suggests that the resistance within the circuit is very low, meaning that there are no significant interruptions or breaks in the wiring.

This low resistance reading indicates that the connections are good, ensuring that electricity can flow freely through the circuit without any barriers. Such readings confirm that the components or sections of the circuit are properly connected and functioning as intended.

In contrast, readings that indicate high resistance would suggest issues such as poor connections, breaks in the circuit, or even open circuits. Understanding this principle is crucial for effective troubleshooting and ensuring that electrical systems operate safely and efficiently.
