The direction of an electric field at any point is the direction a small positive test charge would be pushed. Field lines go from positive to negative.
Between parallel charged plates, the field is uniform: the lines are straight, parallel and equally spaced, and the force on a charge is constant everywhere between the plates.
Around a point charge, the field is radial: lines spread outward from a positive charge or inward toward a negative charge.
