The voltage difference between any two points in a circuit is known as Potential Difference and it is this potential difference that makes current flow.
  
Unlike current which flows around a closed electrical circuit in the form of electrical charge, potential difference does not move or flow it is applied.
The unit of potential difference generated between two points is called the Volt and is generally defined as being the potential difference dropped across a fixed resistance of one ohm with a current of one ampere flowing through it.
In other words, 1 Volt equals 1 Ampere times 1 Ohm, or commonly V = I*R.
Ohm’s Law states that for a linear circuit the current flowing through it is proportional to the potential difference across it so the greater the potential difference across any two points the bigger will be the current flowing through it.
For example, if the voltage at one side of a 10Ω resistor measures 8V and at the other side of the resistor it measures 5V, then the potential difference across the resistor would be 3V ( 8 – 5 ) causing a current of 0.3A to flow.
