A) The difference between electric potential and eletric fields is that electric potential is defined as "the potential energy per unit charge" and an electic field is something that extends outward from every charge and permeates all of space. I've interpreted this as meaning that electric potential is measurement of energy for every charged particle in an electric field, which is the area where all of the charged particles exist. The main difference between the two is that a field is an area of electic currents and electric potential is the potential energy for each charged particle in the field.

B) The difference between electric potential and electric potential energy is that electric potential is the potential energy in each unit charge of a charged particle. Electric potential energy, or difference in potential, is the difference in electric energy between two points, A and B, and how much force is needed to move the charge from B to A. Electric Potential is the electric energy in only one charged particle, where potential difference is the potential energy between to different charged particles, measuring the force needed to move a charge from one particle to another. This is the difference between Electric Potential and Electric Potential Energy, or potential difference.

A) Electric Potential is the potential energy per unit charge. The difference of the two is a field of electric currents and the electic potential is the potential energy specific for each of the charged particals located in the field.

B) The potential energy in each unit charge from each charged partical is electric potential. The difference between 2 points is electric potential energy,

1. The difference between eletric potential and electric field is that electric potential is the potential energy per unit charge and is represented by V. The eletric field however is a vector and is also the area of space that extends out from each of the particles. Therefore an electric field is made up of many different electric particles.

2. As stated above electric potential is the potential energy a particle has per unit charge. Electric potential energy is the difference between two points, it also deals with the amount of force that is required to move the charge from one point to another.

A) Electric potential is the potential per unit charge and the electric field is the force that is exerted onto a tiny positive test charge.  Therefore, an electric field represents the entire force while electric potential is just the potential per each unit charge.

B) Electric potential is the potential per unit charge while electric potential energy is the potential energy that is present between two different points.  It also deals with how much energy or force is needed to move a charge from one point to another.

A)     Electric potential is defined as the potential per unit charge.  An electric field is defined as the force applied to a tiny positive “test” charge.  An electric field measures the force on one certain charge, while the electric potential measures the potential that that one charge has. 

 

B)     Electric potentional measure the potential energy a particle contains per unit charge.  While electric potential measures on particle, electric potential energy measures the difference between two particles, and the amount of force needed to move one particle to another.  In other words, how much force is needed to move particle A to particle B.

a) Electric potential is the potential energy per unit charge while electric field is the force per unit charge.

b) Electric potential is the potential energy per unit charge while electric potential energy is the difference in potential energy between two points and is equal to the work done in getting the charge from one point to the other.
