That is correct. At its heart, a voltmeter is just a microammeter, and it registers current, not voltage. However, that current is very, very small in comparison to the circuit being tested, so this is generally not an issue. Internally, the voltmeter places a large resistor in series with the microammeter, converting it, by Ohm's Law, into a voltmeter.
You don't get something for nothing in this world. No matter how sensitive the voltmeter, in order to register an effect, you have to draw some current. The only alternative, which would not be viable outside of the lab, is to build a voltage source and make a bridge - this way you would not draw any current from the circuit under test - but that is not the way it is done in practice.

How should voltmeter be connected to measure the potential difference across a resistor - in series or in parallel?
In parallel.
Q 1 Name a device that helps to maintain the potential difference across a conductor?
voltmeter
What does a voltmeter do and how is it used to measure electrical potential difference?
A voltmeter is a device used to measure the electrical potential difference between two points in a circuit. It works by connecting the voltmeter in parallel with the component or circuit being measured. The voltmeter then displays the voltage difference in volts, allowing the user to determine the potential difference between the two points.
Uses of voltmeter?
A voltmeter is used to measure the difference in electric potential ("voltage") between two points, usually but not necessarily in an electrical circuit..
How can one determine the potential difference between two points in a circuit?
To determine the potential difference between two points in a circuit, you can use a voltmeter. Connect the voltmeter across the two points you want to measure and the reading displayed on the voltmeter will indicate the potential difference between those two points.
Which of these is used to measure potential difference in parallel circuits?
voltmeter
How is the potential difference across a resistor measured?
by using voltmeter
How is a voltmeter connected in the circuit to measure the potential difference between two points?
The voltmeter is connected in parallel between the two points whose potential difference is required.
How is a voltmeter connected in a circuit to measure electrical potential difference?
A voltmeter is connected in parallel to the component or circuit being measured to measure the electrical potential difference, also known as voltage. This allows the voltmeter to read the voltage across the component or circuit accurately.
What is a voltmeter?
a calibrated instrument for measuring the potential difference between two points.
When measuring the potential difference across a componet you need?
A voltmeter connected in parallel.
Does voltmeter measures the energy converted by a component?
No, a voltmeter measures the difference in electric potential between two points in a circuit, which is called voltage. It does not measure the energy converted by a component, but rather the electrical potential difference across that component.
