Voltage
Voltage measures the electrical potential between two parts of an electrical circuit. Also called electromotive force. Voltage provides the 'pressure' to drive electrons round a circuit.
When a ball is dropped, it no longer has potential energy. Before it drops, you can calculate the potential energy (= mgh); to actually measure this, you would have to measure the force, and multiply that by the distance.
the purpose of a voltmeter is used to measure voltage in a circuit
It would not be the potential energy because potential is the measure of energy that is not in motion yet. When you measure the temperature and it reads 200 degrees YOU WILL FEEL IT because the objects molecules are in motion. If you measured its potential energy at this point of 200 degrees it would probably be close to zero if not zero. When you measure the temperature you are measuring the kinetic energy. The kinetic energy is the measure of how much energy the molecules have that are in motion.

AMPERE - A unit of measure for the flow of current in a circuit. ... the same direction along a conductor from a point of high potential to one of lower potential.

A voltage test meter is used to measure voltage potentials in a circuit.
Amperage or Amps is a measure of is the flow rate of electrical current that is available.
You measure voltage using a voltmeter which involves measuring the electrical potential difference between 2 points in an electrical circuit.
A potential transformer steps the high voltage down to a level of 120 V to measure them safely and easily.
