Question

WHAT IS CONTINUITY???????????

Answer 1

Continuity is the presence of a complete path for current flow. A closed switch that is operational, for example, has continuity.

A continuity test is a quick check to see if a circuit is open or closed. Only a closed, complete circuit (one that is switched ON) has continuity.

During a continuity test, a digital multimeter sends a small current through the circuit to measure resistance in the circuit.

A meter with a continuity beeper briefly sounds off when it detects a closed circuit. The level of resistance needed to trigger the beeper varies by meter, but most will indicate continuity with a measurement between 0-50 ohms.
