Q:

# What is a uniform electric field of magnitude?

A:

A uniform electric field of magnitude is a field that maintains a constant charge throughout and does not change over time. In a uniform electric field, the positive and negative ends of the field are the same at all points. The magnitude of this field is the strength expressed as a vector quantity.

The equation used to find the uniform electric field of magnitude is the amount of force divided by the charge. An electric charge creates an electric field, and is typically symbolized with the capital letter "Q." To measure this charge, another test charge must be placed somewhere within the electric field. The test charge is symbolized with the lower-case letter "q." The test charge receives an attractive or repulsive force when it is placed in the field, and this force is symbolized by "F."

Supposing the magnitude is symbolized by "E," the equation to find the magnitude of an electric field is E = F / q.

Test charges must be used to find the magnitude of a uniform electric field because force requires two sources either pulling toward or against one another. The power of the test charge does not matter according to Coulomb's law, because the more power a test charge has, the more force is present to counter it.
