Potential difference, also known as voltage, is the difference in electric potential between two points in an electric field. It is measured in volts (V) and represents the amount of energy required to move an electric charge from one point to another.
An electric field is a region in space where electrically charged objects experience a force. It is created by electric charges and is represented by lines of force that show the direction and strength of the force.
A uniform electric field is a field with a constant strength and direction. This means that the field lines are evenly spaced and parallel to each other. It is typically produced by two parallel plates with opposite charges.
In a uniform electric field, the potential difference between two points is directly proportional to the distance between them. This means that the greater the distance, the greater the potential difference. It is also affected by the strength of the electric field, with a stronger field resulting in a larger potential difference.
The unit of potential difference in a uniform electric field is volts (V). One volt is equivalent to one joule per coulomb, which represents the amount of energy required to move one unit of electric charge (coulomb) between two points in an electric field.
