# E-Potiential Difference in Uniform Field

• IvaNMK
In summary, E-Potential Difference, also known as electric potential difference or voltage, is the difference in electric potential between two points in an electric field. It is measured in volts (V) and is a measure of the work needed to move a unit charge from one point to another. It is calculated by dividing the work done in moving a charge between two points by the magnitude of the charge. E-Potential Difference plays a crucial role in understanding the behavior of electric fields and is used in many practical applications. It differs from E-Field Strength, which is a measure of the strength of the electric field at a particular point. E-Potential Difference can be negative, indicating that the electric field is directed in the opposite direction

My Question is the - sign in front of the equation Delta V = Ed , or Delta V = - Ed, Which one is true?

Delta V = Ed , or Delta V = - Ed ??

## The Attempt at a Solution

Take mgh as an analogy. Displacement in the direction of the field
decreases the potential (energy).

## 1. What is E-Potential Difference?

E-Potential Difference, also known as electric potential difference or voltage, is the difference in electric potential between two points in an electric field. It is measured in volts (V) and is a measure of the work needed to move a unit charge from one point to another.

## 2. How is E-Potential Difference calculated?

E-Potential Difference is calculated by dividing the work done in moving a charge between two points by the magnitude of the charge. Mathematically, it is expressed as V = W/q, where V is the potential difference, W is the work done, and q is the magnitude of the charge.

## 3. What is the significance of E-Potential Difference?

E-Potential Difference plays a crucial role in understanding the behavior of electric fields. It determines the direction and magnitude of the electric field, and also affects the motion of charged particles within the field. It is also used in many practical applications, such as in batteries and electrical circuits.

## 4. How does E-Potential Difference differ from E-Field Strength?

E-Potential Difference and E-Field Strength are related but distinct concepts. While E-Potential Difference is a measure of the difference in electric potential between two points, E-Field Strength is a measure of the strength of the electric field at a particular point. E-Field Strength is directly proportional to E-Potential Difference, and both are dependent on the distance between two points and the magnitude of the charges involved.

## 5. Can E-Potential Difference be negative?

Yes, E-Potential Difference can be negative. A negative E-Potential Difference indicates that the electric field is directed in the opposite direction to the movement of a positive charge. This is often the case when the electric field is created by a negatively charged object.
