Question

What is a uniform electric field?

Answer 1

1. The space surrounding an electric charge or a group of charges in which another charge experiences a force is called an electric field.
2. A uniform electric field is a field in which the value of the field strength remains the same at all points.
3. If an electric field has the same magnitude and same direction everywhere in a given space then the electric field is said to be uniform.
4. The mathematical relation for the uniform electric field:
   $$\begin{gathered} \mathrm{uniform}\mathrm{electric}\mathrm{field}=-\frac{\mathrm{change}\mathrm{in}\mathrm{potential}}{\mathrm{change}\mathrm{in}\mathrm{distance}} \\ \mathrm{E}=-\frac{∆\mathrm{V}}{∆\mathrm{s}} \end{gathered}$$
5. Parallel plates produce a uniform electric field.
6. In a uniform electric field, electric field lines are evenly spaced.
