If E=-∇V, does it mean that negative voltage emits positive electric field, and positive v negative ef?

An electric field is a physical field that surrounds an electrically charged particle and exerts a force on other charged particles within its proximity.
Electric field and voltage are closely related. Voltage is the measure of the potential difference between two points in an electric field. It represents the amount of energy required to move a charged particle from one point to another within the field.
The strength of an electric field is measured by the force exerted on a unit charge (in Coulombs) placed at a specific point in the field. It is represented by the unit Newtons per Coulomb (N/C).
The formula for calculating electric field strength is E = V/d, where E is the electric field strength in N/C, V is the voltage in volts, and d is the distance between the two points in meters.
The direction of the electric field is always from the higher voltage point to the lower voltage point. This is because the electric field always moves in the direction of decreasing voltage, similar to how water flows from a higher to lower elevation.
