Question

define potential of a point

Answer 1

potential at a point is defined as the amount of work done in moving a unit positive charge from infinity to thatpoint

Answer 2

Heya ! Here is u r Ans >
____________________________________
the electric potential at a given point is the magnitude of potential point at that point per unit charge. But a much better definition is: electric potential at a point is defined as the amount of work done in moving a unit positive charge from infinity to thatpoint.

.

The electric potential (voltage) at any point in space produced by a point charge Q is given by the expression below. It is the electric potential energy per unit charge and as such is a characteristic of the electric influence at that point in space.
