What are the maxwell equations??

I think the simplest way to define an electric field is mathematically. That equation is E=kQ/r^2

E is electric field in Newtons per coulomb
k is the coulombs constant which is 9E9 (the units are Nm^2/C^2)
Q is the present charge in C
r is the distance away from the charge in meters

That's the simplest way to define an electric field I think.

The other way to define an electric field is by using this equation

F/q=E

F is the force between 2 electric particles in Newtons
q is the charge measured in coulombs

hope this helps

The force per unit charge that a positive charge would experience if it were to be inserted into a region of space, where the force is caused by the existence of one or more other charges.

Hover said: E=kQ/r^2
But it wasn't part of the question to assume that the field is caused by one point charge. For example, between two charged parallel plates the electric field is close to being a set of parallel lines with constant magnitude.

Checkout the attached PDF...those are the parts of my notes.

An electric field is an area of space where something experiences a force due to its charge

An electric field is an area of space where something experiences a force due to its charge

True, but the same can be said about a magnetic field too in the case of moving charges.

This may be true, but that is the formal definition of an electric field
