The electric field can be studied in terms of electric field intensity.
a. What is an electric field?
Define electric field strength. Given its unit and dimensional formula.
c. Who introduced the concept of electric field?
d. Is electric field a scalar quantity or a vector quantity?

Explanation

a. Electric field referes to the region surrounding a charge where its influence is felt. The space where charges or charged bodies electrically interact is called elctric field.
b. Intensity of electric frield or electric field strength at any point is defined as the electric force per unit positive charge placed at that point.
Unit `NC^(-1)" Dimension "[M^(-1) L^(-1) T^(-3) A^(-1)]`
c. Micheal Faraday
d. A vector quantity.
