Question: 1 / 400

What will the voltmeter read if the skin of the unit is not hot?

1 volt

5 volts

0 volts

When the skin of the unit is not hot, it indicates that there is no significant voltage present across the skin. A voltmeter measures the difference in electrical potential between two points. If there is no voltage, the voltmeter will read zero volts. This scenario suggests that the unit is functioning properly with respect to electrical insulation and safety, as there should be no leakage current or voltage present that could pose a risk. Therefore, the voltmeter reading of 0 volts confirms that there is no electrical activity or fault in the unit’s skin, supporting the interpretation of safe operational conditions.
