When a technician uses a voltmeter he or she can measure the power going through a circuit. It can test the safety and reliability of a an appliance also.
Another Answer
A voltmeter is used to measure the potential difference, or voltage, between conductors. To measure power (as mentioned in the original answer) you need a wattmeter, not a voltmeter.

What is the voltmeter reading this time?
positive terminal
What happens when a voltmeter is connected in series with load?
when we connected voltmeter in series it takes large current and voltage and the resistance is considerably decreases.this is why we had connected voltmeter in series combination.

How should a ammeter and voltmeter be connected in circuit?
Ammeter is coneccted in series with circuit but Voltmeter is connected in parallel.
How do you convert voltmeter to ohmmeter?
First you will need a constant current source. Do NOT connect the voltmeter to the constant current source without the resistor to be measured already connected. Do NOT use a battery, it is a voltage source. Then follow these steps to measure a resistor:connect the voltmeter across the resistor to be measuredconnect the voltmeter-resistor combination across the constant current sourceread the voltmeter and record the voltagedisconnect the voltmeter-resistor combination from the constant current sourcedisconnect the voltmeter from the resistorcalculate the resistance from the measured voltage and current from the source with Ohm's law in this form: R = V ÷ IIts much easier to just use the ohms setting on a multimeter.
What should a technician do to determine that the plus 5V rail on the power supply is outputting 2.2 Volts?
A voltmeter will show the voltage on the rail and a technician will know how to use one.

What is a sentence for voltmeter?
A voltmeter is a device used to measure the voltage in an electrical circuit. An example sentence would be: She went to the hardware store to purchase a voltmeter.
How does a electrodynamometer work as a voltmeter?
An electrodynamometer can work as a voltmeter by judging the wavelength and force of the electricity, much the same at the voltmeter, then converting it to a force that is more recognizable.
Which voltmeter will used for measuring 50kv dc?
Any standard voltmeter but however the voltage to be measured must be stepped down to a safe value using a Potential transformer.
