work - What does electric potential mean in a circuit?


As we know that electric potential at a point is defined as a work done by me to carry unit charge from infinity to that point. How can I use this definition in an electric circuit that contains a battery? Suppose electric potential at a point in a circuit is 4 volt. What does this means? l. Is it means that work done by me to carry unit charge from infinity to that point in a circuit is 4 Joules?
