Uniform Electric Field and Potential Difference
Uniform Electric Field
A uniform electric field is a type of electric field wherein the direction and magnitude of the electric field is constant throughout the space. It is a special case of an electric field wherein the lines of force are straight and parallel to each other.
Potential Difference
Potential difference is the difference in electric potential between two points. It is also known as voltage and is measured in volts (V). The potential difference between two points represents the amount of work done per unit charge in moving a charge from one point to another against the electric field.
Calculation of Potential Difference
The potential difference between points A and B in a uniform electric field can be calculated using the formula:
V = Ed
Where V is the potential difference, E is the electric field strength, and d is the distance between points A and B.
Explanation
In a uniform electric field, the electric field strength is constant, and the lines of force are straight and parallel. Therefore, the potential difference between two points A and B in the field is directly proportional to the distance between them. The greater the distance, the greater the potential difference.
For example, if the electric field strength of the uniform electric field is 100 N/C, and the distance between points A and B is 2 meters, then the potential difference between points A and B is:
V = Ed = 100 N/C x 2 m = 200 V
Conclusion
The potential difference between points A and B in a uniform electric field depends on the electric field strength and the distance between the points. The greater the electric field strength and the distance between the points, the greater the potential difference.
