What is the physical significance of electric field

dear deepanshi 
a field in physics means a physical object that have a finite value everywhere in given region of space . 
el;ectric field is a space around  charged object where the influence of charge can be felt . 
now as a charge can experience force due to anathor charge , thus the influence here become the force , so. E.F can be called as a force field too . 
mathematically , in this case electric field intensity , which is force experience by a test charge placed at that point of the field gives the estimate of strength of field at that point .
