The Continuity Testing Lamp Bulb is a diagnostic tool used to test non energized electrical circuits for continuity and resistance levels. When connected across a low resistance circuit, the lamp illuminates brightly, clearly indicating a complete circuit path. If the resistance of the circuit exceeds ten ohms, the lamp does not illuminate, helping identify open or high resistance conditions.Attributes:• Provides visual indication of circuit continuity.• Illuminates brightly across low resistance circuits.• Does not illuminate when circuit resistance exceeds ten ohms.Applications: The Continuity Testing Lamp Bulb is used as a tool in electrical maintenance and troubleshooting to check continuity and resistance in non energized circuits during field and workshop inspections.
