A Volt meter is used to measure potential difference (a.k.a. voltage).
Potential difference is measured in units called: Volts (V).

There is no difference between potential difference and potential drop. Both terms refer to the difference in voltage (i.e. potential) across a component. Depending on how you look at it, both terms can refer to positive or negative differences, i.e. drop, for instance, can be negative, implying a rise.
A transformer is an electrical device that takes electricity of one voltage and changes it into another voltage. You'll see transformers at the top of utility poles and even changing the voltage in a toy train set.
You can compare 'potential' with height, and 'potential difference' with the difference in height.The height of an object depends upon from where you measure it. For example an object three-quarters of the way up a 1000 m mountain is +750 m from the base of the mountain, but -250 m from the top of the mountain. Note how we apply a positive or a negative sign to indicate whether we are measuring upwards or downwards.The same applies to potential. It's value depends upon from where it is measured. For example, two charged objects could have a potential of , say, +5 V with respect to earth (ground) and a potential of -15 V with respect to earth. But the potential difference between them will be +5 - (-15) = 20 V.Notice how, in the above example, we always show a positive or negative sign when we talk about potential, but we don't use these signs when we talk about a potential difference. Furthermore, it is important that we must ALWAYS specify the reference point when we describe potential -e.g. "What is the potential at point A, with respect to (say) earth?"Taking this further. It's important to know that the term 'voltage' means 'potential difference', and not'potential'! It would be quite wrong to say that the 'voltage of an object is (say) -200 V with respect to earth'. The correct expression would be the 'potential of an object is -200 V with respect to earth'.
voltmeter
A voltage test meter is used to measure voltage potentials in a circuit.
A voltmeter is used to measure the difference in electric potential ("voltage") between two points, usually but not necessarily in an electrical circuit..
A voltmeter is used to measure electric potential, which is also known as voltage. It is a device that is typically connected in parallel to the circuit or component being tested to measure the potential difference between two points.
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.
