Chapter 21, Problem 69A

To determine

To Define:Volt in terms of change in potential energy moving in an electric field.

Explanation of Solution

Introduction:

Electric potential difference refers to the amount of energy required to bring a unit charge from a point of reference to a point in an electric field. Electric potential energy refers to the amount of energy required to a move a charge from one point to another against an electric field.

The relationship between electric potential and potential energy is:

$\Delta V=\frac{\Delta U}{q}$

Here, $\Delta V$ refers to electric potential difference, $\Delta U$ refers to electric potential energy and q is the charge.

Therefore, 1 volt can be defined as the difference in the electric potential energy to move a unit charge from one point to another, against an electric field.
