Potential is nothing but work done to move a charge from infinite point to a particular point.potential difference is nothing but work done to move a charge from one point to another point.There is a lot of difference between these two.
Let us assume that point C is at zero potential,In order to move unit charge from A to C we need 10 volts,In order to move charge from B to C we need 6 volts,so voltage between A&B is 4 volts. potential difference or voltage can be defined as work done per unit charge.
potential difference = work done / charge.
The unit of voltage is "volt". one volt is defined as one joule of energy required to move a one coulomb of charge.
We are moving a unit charge from A to B by doing work 4 joules,so 1 volt(4 joules/1 coulomb).
can you explain breifly?
