The discussion revolves around the concepts of potential and potential difference in the context of electric circuits, as outlined in Chapter 34 (Electric Current). Participants seek clarification on these terms and their definitions as presented in the textbook.
Some participants have offered definitions and comparisons to gravitational concepts, indicating a productive exploration of the topic. However, there is no explicit consensus on the definitions, and further questions remain regarding the textbook's explanations.
Participants note the importance of the textbook reference for understanding the terms and express a need for clearer definitions. There is an acknowledgment of the complexity of the concepts being discussed.
What is the book - the reference is meaningless without this information.Chase25 said:So I'm supposed to read Chapter 34 (Electric Current) in the next couple of days.
The book should have defined the terms. Reread those bits.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.
Thanks!Simon Bridge said: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.
