A DC voltmeter can read an electrostatic field's potential since it can measure a non-changing voltage.
However, a electrostatic charge is by definition non-moving. When it does move, it becomes a direct current.

What are the direct current instruments and measurements?
D.c GeneratorComputers=======================DC voltage is measured with a voltmeter.DC current is measured with an ammeter.That's all there is to measure in a DC circuit.
What is difference between ac and DC bulb?
we can check the dc with the help of tester give the reasonAnswerThere is no such thing as an 'AC light bulb' and a 'DC light bulb'. A light bulb doesn't care whether it is subjected to AC or to DC.
What is the difference between ac Hall effect and dc Hall effect?
ac hall effect always rises and dc is always in steady state.................
In a photovoltaic power plant what is the purpose of the inverter?
Ernie Ramhoff
Can amps go up if volts goes down in AC?
No, Ohms Law applies equally well in ac as in dc.
Can DC ampere be measured with AC amp meter?
No. The ammeter must be designed to measure DC. Some clamp-on ammeters are designed to measure both AC and DC.
Can you measure ac mains voltage with dc voltmeter or high dc voltage with ac meter?
You cant.
What instruments do AC to dc current use?
I would assume that you mean what devices do you use to convert ac current to dc current?The answer is Diodes.seediode-bridge
How many things can a multi meter measure?
Resistance Voltage (both AC and DC) Current (both AC and DC)
What value of voltage measure by DMM Vrms or Dc voltage?
Many can measure both - Vrms (AC) or DC voltage.
Why pmmc instrument measure only ac not dc?
Permanent magnet moving coil instruments are used for measuring d.c. quantities only. This is so because for these instruments the torque is proportional to the operating quantity either voltage or current.
What are the three main function of the multimeter?
A typical multimeter can measure: * AC & DC voltage (volt) * AC & DC current (amp) * resistance (ohm)
Why can't AC be measured by a Volt Ohm Meter?
Typical VOMs can measure both AC and DC.
Why use AC to measure ionic conductance and why not dc current?
in order to avoid electrolysis
What is the different between ac ammetter and dc ammetter?
A: No different just the first measure A.C. the other measure D.C.
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.
Is there any possibilty of ac and DC flows in conductor at a time and get DC and AC with two reference AC and DC?
A typical AC waveform is symmetrical about a zero crossing point. You can bias the AC with DC such that the AC waveform is symmetrical about the DC voltage.
