  • In the same way, as you do work on a charge to move it closer to another charge of the same sign, you increase the electric potential energy. That's because like charges repel each other, so it takes more and more energy to move the charges together the closer you get.

When a free positive chargeqis accelerated by an electric field, such as shown inFigure 19.2, it is given kinetic energy. The process is analogous to an object being accelerated by a gravitational field. It is as if the charge is going down an electrical hill where its electric potential energy is converted to kinetic energy.

This is because the electric field is uniform between the plates. In more general situations, regardless of whether the electric field is uniform, it points in the direction of decreasing potential, because the force on a positive charge is in the direction of E and also in the direction of lower potential V.

E= V d cos() (6) When a charged particle moves in an electric eld, if its electric potential energy decreases, its kinetic energy will increase. In other words, the total energy is conserved. A positive charge placed in an electric eld will tend to move in the direction of the eld.

Electrical Charges could be positive or negative. Thus electrical forces could be attractive or repulsive. Some agreed upon conventions have been arrived at so that we all speak the same language. Electric Fields have lines that travel from a posi...

$\begingroup$ Why does the magnitude become smaller? If work is required to move the charges apart, the magnitude of potential energy should increase as the distance between them increases. That is what I don't get. $\endgroup$ – A.AK Sep 16 '17 at 20:09

Likewise, negative charges are accelerated up gradients in the electric potential. According to Eq. , the -component of the electric field is equal to minus the gradient of the electric potential in the -direction. Since there is nothing special about the -direction, analogous rules must exist for the - and -components of the field.
