Did you mean "The strength of electric field is positive or negative"?
Anyway, there is your answer..
The strength of an electric field E at any point is defined as the electric force F exerted per unit positive electric charge q at that point, or E = F/q.You can say that it is positive.
The electric field points from positive to negative.
In a given system, the electric field direction changes from positive to negative when the source of the electric field changes its charge from positive to negative.
The strength of the electric field between positive and negative charges is determined by the magnitude of the charges and the distance between them. The direction of the electric field is from the positive charge to the negative charge.
Electric field lines go from positive charges to negative charges.
A negative point charge will be attracted towards a positive point charge in an electric field.
The electric field points from positive to negative.

Electric field lines go from positive charges to negative charges.
Electric Field between positive and negative charges. If the Electric Field in which both the positive and negative charges are present is stronger than the Electric Field between the two charges we are talking about, the the negative charge will move away from the positive charge in that positive direction of the field. If not, then the negative charge will get attracted to the positive charge and stay at the position of the positive charge. It will be pulled toward the source of the electric field. (Novanet)
A negative charge is caused by a excess of electrons and a positive charge by their lack.
A negative point charge will be attracted towards a positive point charge in an electric field.
That is not correct. Electric field lines originate from positive charges and terminate on negative charges. In the case of a uniform electric field, the field lines run from the positive plate to the negative plate.
Because opposite charges attract. The negative end of the dipole moment is trying to get to the positive end of the field, and the positive end of the dipole is trying to get to the negative end of the field.
A positive electric field strength indicates that the field is directed away from a positive charge or towards a negative charge. It signifies the direction in which a positive test charge would move if placed in the electric field.
No. Any charged object ... the positive and negative ions in table salt, for example... emits an electric field.
Either a positive or a negative test charge can be used to determine an electric field. The direction of the electric field will be defined by the force experienced by the test charge, with the positive test charge moving in the direction of the field and the negative test charge moving opposite to the field.
