You will not get a measurement. depending on what kind of measuring device you use the socket could begin to smoke and the voltmeter will fly out (happened to me).

∙ 15y agoThe average instantaneous voltage of an AC waveform is zero, since the positive peaks cancel out the negative peaks. A DC voltmeter will register zero or very close to it.

How is the potential difference across a resistor measured?
by using voltmeter
What you measure voltage into?
You measure voltage using a voltmeter which involves measuring the electrical potential difference between 2 points in an electrical circuit.
How do you measure the resistance of a motor?
we can measure the resistance of the motor by using voltmeter ammeter method of by directly using a multimeter across the armature terminals of the motor in voltmeter ammeter method we should use a less value of dc voltage to find the resistance
What would happen if a voltmeter were substituted for an ammeter?
Smoke. Since a voltmeter is in parallel with the load it is right across the source voltage. Putting the amp meter across the line with its low resistance it will act like a fuse, hence the smoke. Newer solid state testers are usually smarter that the operators. They have built in circuitry which sense the wrong settings you are using and shut the tester off with a "beep" to let you know that you are doing something wrong.
Will dc voltmeter measure ac voltage?
Yes, if you provide a rectifier to convert the AC into DC. This is how early AC voltmeters worked. They rectified the AC into DC, and the DC voltmeter measured something related to the peak voltage. In order to calibrate, you then considered that RMS voltage is peak voltage divided by the square root of 2. The problem with that approach is that it only works for sinusoidal AC. If the AC is some other shape, such as square or triangular, then the calibration does not work correctly. Modern AC voltmeters measure true RMS using signal processing techniques. If you attempt to measure AC with a DC voltmeter without a rectifier, it may or may not work, depending on the design of the meter. An ordinary VOM style meter would read zero, because the average voltage of an AC waveform is zero.
How voltage measured?
It is measured using a Voltmeter
How is voltage measured?
Use a voltmeter with a high input impedance and measure at the source the voltage.
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.
How is the potential difference across a resistor measured?
by using voltmeter
How do you measure voltage?
Voltage can be measured using the difference between the potentiel between two ends of wire or by using a volt-meter. You can easily measure volt by volt or multimeter but remember voltage always measure across the components but in parallel
What do volts do?
the amount of energy of electrons is measured in volts by using a voltmeter
What you measure voltage into?
You measure voltage using a voltmeter which involves measuring the electrical potential difference between 2 points in an electrical circuit.
How do you calculate low phase voltage of a three phase four wire system without using voltmeter?
The formula you are looking for is - phase voltage/1.73 = phase to neutral voltage.
What is the Disadvantage of using an ammeter and voltmeter to measure resistance?
There will be errors. The error comes from the measured resistance size of the decision.
How do you measure rms value of complex waveform?
rms value is measured using voltmeter with the use of heat sensing elements.
How do you check output voltage from SMPS when it is not connect to motherboard?
If someone wants to check the voltage from SMPS even without it being connected to the motherboard that can be done by using a voltmeter. This if connected carefully can indicate the voltage.
How do you measure the current by using multimeter?
The current is the amperage. It is measured in series. Voltage is measured across the line (parallel).
