1.)In an electric potential the charge is moving from infinity to a given point.
Is that infinity point is within the electric field or outside of it?
2.)Is electric potential difference and voltage are same?
3.)Are electric potential and voltage same?
1.) In order to determine whether the infinity point is within or outside of the electric field, we need to understand the concept of electric potential and how it is related to the electric field. Electric potential refers to the electric potential energy per unit charge at a given point in an electric field. Electric potential is directly related to the electric field and is determined by the distribution of charges and the distance from the charges.
When a charge moves from infinity to a given point, it means that the charge is initially infinitely far from any other charges and is being brought towards a specific location. If the charge is moving towards a point within an electric field, it means that the point is within the influence of the electric field and the charges creating it. In this case, the infinity point would be within the electric field.
On the other hand, if the charge is moving towards a point outside of the electric field, it means that the point is not within the influence of the electric field. In this case, the infinity point would be outside of the electric field.
2.) Yes, electric potential difference and voltage refer to the same concept. Electric potential difference, often referred to as voltage, is the difference in electric potential between two points in an electric field. It represents the work done per unit charge in moving a charge between those two points. The terms "voltage" and "electric potential difference" are used interchangeably and describe the same physical quantity.
3.) Electric potential and voltage are often used interchangeably in everyday language, but in a more technical sense, they have slightly different meanings. Electric potential is a scalar quantity that represents the electric potential energy per unit charge at a specific point in an electric field. It describes the potential for electric energy at that point.
On the other hand, voltage is a measure of the electric potential difference between two points in an electric field. It represents the work done per unit charge in moving a charge between those two points. While both terms are related and used to describe the electric potential energy, they have slightly different interpretations.
In summary, electric potential refers to the potential energy per unit charge at a specific point, while voltage refers to the potential energy difference between two points in an electric field.
