The old voltmeters were an ammeter in series with a resistor (which set the range).
Digital voltmeters may sense voltage directly or current through a resistor -
and then use digital circuits to convert the reading into alpha-numerics.

What is the purpose of a voltmeter in a circuit?
the purpose of a voltmeter is used to measure voltage in a circuit
Describe the proper placement of a voltmeter in a circuit?
A voltmeter should be connected in a parallel connection
What is the ideal voltmeter high or low?
Ideal Voltmeter has an infinite resistance so it won't draw current from the circuit, but in real life ideal voltmeter doesn't exist.
How do you connect an ammeter and voltmeter?
The voltmeter is connected across the supply and the ammeter is connected in series with the supply.
Why potentiometer is preferred on voltmeter?
no
When was the Volt Meter invented?
Voltmeters were made possible by an 1819 discovery by Hans Oersted. The first voltmeter were made soon after that.
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.
How long does it take for a voltmeter to work?
If it's an analog voltmeter, it will work as soon as a voltage is applied. If it's a digital meter, it will need to be turned on first, but will respond instantly once it is powered up.
Is a voltmeter placed parallel to a circuit?
Depends. What did you want to measure? If it's voltage drop across the incandescent element, then you had better hook up your infinite resistance voltmeter in parallel with the lamp.
What is the voltmeter reading this time?
positive terminal
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 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 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.
