Question

Continuity of electrical circuit is checked by .

• A. Ammeter
• B. Voltmeter
• C. Ohm meter
• D. Megger

Answer 1

The Correct Option is D

Continuity in an electrical circuit means that the path for current flow is complete without any breaks. To check continuity, a device that measures insulation resistance and detects breaks or faults in the circuit is used.
A Megger is an instrument specifically designed to measure high resistance values, commonly used to test the insulation quality and continuity in electrical circuits. It applies a high voltage to the circuit and measures resistance, helping to identify breaks or faults.
Ammeter measures current flow but does not check continuity.
Voltmeter measures voltage across points in a circuit.
Ohm meter measures resistance but generally for lower resistance values and simple continuity checks.
Megger is preferred for checking insulation resistance and ensuring continuity, especially in electrical wiring and equipment.
Hence, the Megger is the correct tool for checking electrical continuity.
