To be specific, a voltmeter is a tool used especially in science to calculate the differences of electric potential of two circuits. There are quite a few types of voltmeters and they are also quite portable which may be ideal for traveling with.

How would you extend the range of a voltmeter and ammeter?
if we would like to expand the range of voltmeter we should change the voltmeter resistance even to be appropriate . we should use a variable resistance to control of its value . I would extend the range of a voltmeter by adding resistance in series with it. I would extend the range of an ammeter by connecting resistance in paerallel with it.
What instrument measures VDC?
A DC voltmeter is ideal.
Why does voltmeter practically not consume any electric energy from the electric circuit?
The resistance used in a voltmeter is extremely high when measuring voltage, which is why the current is low (I = E/R).
Why does voltmeter measure current more accurately than an ammeter?
A voltmeter does not measure current, it measures voltage in units named volts. An ammeter measures current in units named amperes or amps in common shorthand. A voltmeter is connected in parallel to the circuit being measured, whereas an ammeter is connected in series with the circuit being measured.
How you can minimize the loading effect on voltmeter?
Loading refers to the phenomena that occurs when a load circuit having low effective impedance is connected to a supply circuit having higher effective impedance.
Voltmeter in series?
No. Voltmeter in parallel. Ammeter in series.
What is a dc voltmeter?
It is a voltmeter which can only measure direct current.
What does a voltmeter measure voltage in?
A voltmeter measures voltage in volts.
Which type digital voltmeter is the of fatest all digital voltmeter?
You mean fastest? Digital voltmeter gives reading in seconds.
What is the voltmeter reading this time?
positive terminal
What is voltmeter?
A voltmeter is a measuring instrument that is used in the measurement of the electric potential in volts.
Why there is an extension range of voltmeter when a series resistance not equal to voltmeter is used?
why is extention
What is the purpose of a voltmeter in a circuit?
the purpose of a voltmeter is used to measure voltage in a circuit
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.
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.
