Top best answers to the question «Does charge affect electric field»
Electric field is the force per quantity of charge on the test charge. The electric field strength is not dependent upon the quantity of charge on the test charge… After all, the quantity of charge on the test charge (q) is in the equation for electric field.

A test charge certainly does affect the electrical field. But if you’re talking about the concept of Potentials, then read carefully: they’re talking about imaginary test-charges which have infinitesimal charge. Any real test-charge will have a significant effect on the e-field being tested.
All charged objects create an electric field that extends outward into the space that surrounds it. The charge alters that space, causing any other charged object that enters the space to be affected by this field.
Yes…in theory Gauss’s Law can be used to find electric field of any stationary charge distribution. Why? because Gauss’s Law is Columb’s law written in a fancy (but useful) way… and as you know Columb’s law is ‘fundamental’. But just because it can be used does not mean that it will be used.
In reality, there is just an electromagnetic field which affects charges, currents, dipoles and such other entities. A simple illustration of this point could be - if you are in a frame of reference in which a charge is at rest, you measure only the electric field.
Since electric chargeis the source of electric field, the electric field at any point in space can be mathematically related to the charges present. The simplest example is that of an isolated point charge. For multiple point charges, a vector sum of point charge fields is required.
