In a region where the electric field is constant, as it is between two oppositely charged parallel plates, is the voltage also constant?

In a region where the electric field is constant, such as between two oppositely charged parallel plates, the voltage is also constant. The electric field is defined as the force per unit charge experienced by a test charge placed in the field. Similarly, voltage (also known as electric potential difference) is defined as the work done per unit charge in moving a test charge between two points.

In this scenario, the electric field is constant because the plates are oppositely charged and parallel to each other. As a result, the electric field strength remains the same across the region. Since voltage is the difference in electric potential between two points, and the electric field is uniform, the voltage is constant between the plates.

To calculate the voltage between the plates, you can use the formula:

V = Ed

Where V is the voltage, E is the electric field strength, and d is the distance between the plates. By multiplying the electric field strength by the distance, you can determine the constant voltage between the parallel plates.
