Red wire from a regular DC voltmeter should be connected to :
An AC voltmeter is ideal. If you really want to get fancy and analytic about it, you could use data-acquisition equipment to constantly read the AC voltmeter, and store or record the data.
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).
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.
yes it can read both ac and dc voltage and current .AnswerThe whole point of a multimeter is that it can perform the function of an ammeter, a voltmeter, and an ohmmeter!
Most true RMS voltmeters can measure the value of a ripple voltage on top of a DC supply, when you place it in AC mode. You can also place a small capacitor in series with a DC voltmeter and that would measure the ripple. The real way to do this, because ripple voltage is not sinusoidal, is to use an oscilloscope, particularly if you want the peak values.
A: It is a regular DC voltmeter but the AC is rectified and the DC component is measured and displayed as AC VOLTS.
You cant.

The voltage across a load in a circuit with alternating current is typically measured using a voltmeter. The voltmeter is connected in parallel to the load, allowing it to measure the effective voltage or RMS voltage across the load. This value represents the average voltage of the alternating current waveform.

If you measure the Instantaneous Volyage using a Voltmeter the1. DC the Voltmeter reading will remain constant it will not change.2. AC the voltage will vary from positive to negative . The variation can be sine wavw, Square wave, triangular wave or any other type.

A multimeter is a device that can measure multiple electrical parameters like voltage, current, resistance, and more. A voltmeter, on the other hand, is a specific type of meter that is used to measure voltage in a circuit. In essence, all voltmeters are a part of a multimeter, but not all multimeters have a separate function as a voltmeter.
