An electric field is an area surrounding a charged particle or object that can exert a force on other charged particles or objects. Although you cannot see an electric field, a non-contact force acts on a charged object when it enters the field.
A non-contact force is a force that acts on an object without physically touching it. Since charged objects don’t need to touch for forces to act on them, this force is considered a non-contact force.
Electric fields are typically represented by electric field lines, which are diagrams with arrows.
The field lines always extend:
The electric fields can be drawn like the diagrams below.
It’s important to note :
In the diagram below is the electric field between two opposite charges.
