Question

To determine the continuity of the windings __________ is used:
1. Frequency Meter
2. Ammeter
3. Multimeter
4. Voltmeter

Answer 1

Correct Answer - Option 3 : Multimeter

Concept:

Continuity:

• Continuity testing is the act of testing the resistance between two points.
• If there is very low resistance, the two points are connected electrically.
• If there is more than a few ohms of resistance, then the circuit is open.

 

Multimeter testing:

• Set the multimeter to 'Continuity' mode.
• Now touch the probes together. The multimeter should emit a tone.
• This shows that a very small amount of current is allowed to flow without resistance.
• Now touch the probes at two different points on the winding if multimeter emits a tone then there exists a continuity between the two points.
• There exists a continuity in the windings.
• If multimeter doesn’t emit tone then the two points doesn’t have a path for the current to flow from one point to another.

 

Other advantages of Multimeter:

• It offers automatic output display.
• It ensures accuracy.
• It has auto polarity functions.
