voltmeter
Yes. I think that is a definition of current.
A voltmeter measures the potential difference between two points,whether or not the two points are in the same circuit.
Voltage (of a circuit) as defined in the NEC: n. The greatest root-mean-square(rms) (effective) difference of potential between any two conductors of the circuit concerned. Voltage as defined by Webster's: n. Electromotive force or potential difference, usually expressed in volts.
Voltage drop
Voltage in an electrical circuit is the rough equivalent of pressure in a water pipe. It causes the electricity to flow. Higher voltage; more flow. The difference is that you can think of pressure applied at a single point, but voltage is always the difference in electrical potential between two points. That's how a bird can stand on a 7,000-volt rural electrical line without harm. The potential difference (voltage) between the line and the ground is 7,000 volts, but the potential difference (voltage) between the bird's two feet is very tiny.
electric potential is potential difference between two points in closed circuit. but electromotive force is potential difference in any open circuit.

A voltmeter is used to measure the difference in electric potential ("voltage") between two points, usually but not necessarily in an electrical circuit..
It is defined as electromotive force, and the difference in electrical potential between 2 points in a circuit. It has also been explained as the pressure in an electrical circuit.
You measure voltage using a voltmeter which involves measuring the electrical potential difference between 2 points in an electrical circuit.
if an electric circuit has potential difference. Electricity will flow only if an electrical circuit is closed.

Volts are a unit of measurement determined by the "electrical pressure" in a circuit, or the potential difference between two charged bodies, say the positive and negative sides of a battery.
