Electric field intensity is a vector quantity that represents the force per unit charge experienced by a positive test charge placed in the field. It is a fundamental concept in electromagnetism, describing how electric forces are distributed in space and influencing how charged particles move within the field.

A vector quantity is a physical measurement that has both magnitude and direction, distinguishing it from scalar quantities which have only magnitude. Vectors are crucial in fields like physics and engineering to describe quantities such as force, velocity, and displacement, and are typically represented graphically by arrows or mathematically by ordered pairs or triplets.
