# The Terms Potential & Potential Difference

So I'm supposed to read Chapter 34 (Electric Current) in the next couple of days. I'm sure I'll have more questions about it but one question I have right now is what does the book mean by the term potential and potential difference. My teacher briefly explained it but I couldn't stay awake this morning so could I have some help?

What is the book - the reference is meaningless without this information.

The book should have defined the terms. Reread those bits.

For electric circuits:
the potential difference is the voltage between two places in the circuit.
the potential is the potential difference between some place in the circuit and some standard reference point like the ground or the negative terminal of the power supply.
the potential energy of a charge is qV - the amount of charge times the potential where it is.
when a charge falls through a potential difference ΔV, it gains kinetic energy qΔV.
