Electrostatic field lines start on positively charged surfaces and end on. Field lines depicting the electric field created by a positive charge left, negative charge center, and uncharged object right. Note that the electric field is defined for a positive test charge q, so that the field lines point away from a positive charge and toward a negative charge. An electric field is a vector quantity whose direction is defined as the direction that a positive test charge would be pushed when placed in the field.
