If the needle of a voltmeter gives a reverse reading, what should be done?

Replace the voltmeter
Change the battery in the voltmeter
Reverse the test lead
Check the circuit for faults

The correct answer is: Reverse the test lead

When the needle of a voltmeter gives a reverse reading, it typically indicates that the leads of the voltmeter are connected incorrectly, meaning the positive lead is connected to a negative voltage and the negative lead to a positive voltage. The correct action in this scenario is to reverse the test leads so that the voltmeter can accurately measure the voltage in the circuit. By switching the leads, the voltmeter will be properly connected and should display a positive reading if the circuit has a positive voltage. This step is essential for obtaining correct voltage readings and ensuring that the voltmeter functions properly in that specific measurement scenario. Replacing the voltmeter or changing its battery may be unnecessary if the issue is simply with lead placement. Additionally, checking the circuit for faults could be a separate troubleshooting step if there are persistent issues, but in the case of a reverse reading just switching the leads is the immediate and correct action to take.
