Electric Field Formula. This electric field is the source of the electrostatic force that nearby charged objects experience. The electric field is a vector quantity, and the direction of the field lines depends on the sign of the source charge. Electric field vectors point away from positively charged sources, and toward negatively charged sources.

1. Electrostatic Field 1.1. Introduction A electrostatic field is a electric field produced by static electric charges. The charges are static in the sense of charge amount (it is constant in time) and their positions in space (charges are not moving relatively to each other). Due to its simple nature, the electrostatic

Get Price ### What is the relation between electric potential and

May 31, 2017The electric field is like any other vector field—it exerts a force based on a stimulus, and has units of force times inverse stimulus. In the case of an electric field the stimulus is charge, and thus the units are NC-1. In other words, the electric field is a measure of force per unit charge.

Get Price ### Relation between Electric field and potential

Hence electric field is the negative gradient of the scalar potential. The negative sign came as a result because the potential difference is the work done per unit charge against the electrostatic force to move a charge from a to b. However, this equation is valid only for static electrostatic fields.

Coulomb's Law and Electric Fields. Electrostatic force is a vector quantity, and so is electric field. The sign of the test charge determines the relationship between the electric field and electrostatic force directions. If the test charge is positive, then the force and field vectors have the same direction.

The electric field - and hence the electric force - can change over time, if the charge particles generating the field are moving. An electric field does not have to be static. Electromagnetic interactions involve moving charges. It includes both electric and magnetic forces. We already learned about electric forces. Magnetic forces are forces acting between magnets. It occurs between a magnet and a piece of iron.
