is it true that the voltage at a point means the quantity of charge at that point?if not then what is voltage?
thanks

Is it true that the voltage at a point means the quantity of charge at
Click For Summary
Discussion Overview
The discussion centers on the relationship between voltage and charge, specifically whether voltage at a point indicates the quantity of charge at that point. Participants explore the definitions and implications of voltage and electric potential.
Discussion Character
- Conceptual clarification
- Debate/contested
Main Points Raised
- Some participants assert that voltage is not the quantity of charge at a point but rather the difference in electric potential between two points.
- It is proposed that voltage relates to potential energy per charge, indicating that it reflects the work done in moving a charge through a voltage difference.
- There is a question raised about the meaning of electric potential and whether it is synonymous with voltage.
- One participant suggests that voltage, potential difference, and electric potential are equivalent concepts.
Areas of Agreement / Disagreement
Participants express differing views on the relationship between voltage and charge, with some clarifying definitions while others seek further understanding. The discussion remains unresolved regarding the nuances of these concepts.
Contextual Notes
Participants express uncertainty about the definitions and relationships between voltage and electric potential, indicating a need for clearer distinctions and explanations.

hi amaresh92! 
no, voltage is a difference between two points …
it's the difference in electric potential between two points
(and since electric potential = potential energy per charge, that means it's the difference in potential energy between two points, for a unit charge)
from the work energy theorem that means that the work done moving a charge q through a voltage difference V is the change in potential energy: Vq

i am not able to understand the term electric potential?Is electric potential and voltage means same?
thanks.

yes, voltage = potential difference = difference in electric potential = difference in potential energy per electric charge
