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

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.
