A volt is a unit of, essentially, electric force. It basically measures how much crud a particular current can go through before it weakens too much. It serves its purpose in that it both allows us to build good transformers and provides another way to transmit huge amounts of power without heating up the wires. It's named after Volta, the sci guy who made the first voltaic pile.

Voltage is also called potential, because it's basically called potential energy. When you study basic circutry (in physics called "solid state physics" ) you get the flow of electricity explained like the flow of water.

The rate at which water/electricity flows is called current and is labeled with the letter I and measured in Ampers (Amps).

The resistance of a pipe or wire to the water/electricity is called resistance and is measured in Ohms (Ω).

The potential the water/electricity starts out at the source is callet voltage and is measured in Volts.

The relationship between these is V=IR. So if you use the water analogy adding more voltage is like raising the water bucket up higher, allowing it to fall further and gather more energy before it reaches a part/pipe of the circuit which has resistance.

A volt is a unit measured by the ratio of Ampere and conductance.
Ampere is a unit of electron power
conductance is a unit of velocity
Volt is an electromotive force.

Hence Electron power = volt(force)*velocity(conductance)
=joules per seconds

volt is the pressure that push electrons through a conduct.that's why more volts more current.
