Electrostatic field

If the electric field of a charge at a point doesn’t vary with the time, then the electric field is called electrostatic electric field. It’s effect on other charges is studied by defining two quantities; one a scalar field function called electric field potential ‘V’ & second a vector field function called electric field intensity  are related as

Here the –ve sign implies that electric field intensity due to both positive & negative charged configuration is always in the direction of decreasing field potential i.e. from a region of high potential to a region of low potential.
