Find the potential as a function of position in the electric field $\vec{E}=a x \hat{\imath}$, where $a$ is a constant and where $V=0$ at $x=0 .$. If the electric field is zero in a particular region of space,

2) must have the same value everywhere in the region,. Find the potential as a function of position in the electric field $\vec{E}=a x \hat{\imath},$ where $a$ is a constant and where you’re taking $V=0$

### Where Is the Electric Potential Equal to Zero? ^{[2]}

In introductory physics textbooks often have some version of the following two problems.. Where is the electric field equal to zero (technically the zero vector)?

Yes, the electric field is a vector and the electric potential is a scalar — so you would think that the question about potential might be simpler, but not so. If you only have two electric charges, the electric field vector can only be zero on an axis connecting the two charges.

It’s actually sort of complicated and at this point, I don’t even know all the answers. I’m going to put one of them at the origin and the other on the x-axis

### Electric potential ^{[3]}

The electric potential (also called the electric field potential, potential drop, the electrostatic potential) is defined as the amount of work energy needed per unit of electric charge to move this charge from a reference point to the specific point in an electric field. More precisely, it is the energy per unit charge for a test charge that is so small that the disturbance of the field under consideration is negligible

By definition, the electric potential at the reference point is zero units. Typically, the reference point is earth or a point at infinity, although any point can be used.

By dividing out the charge on the particle a quotient is obtained that is a property of the electric field itself. In short, an electric potential is the electric potential energy per unit charge.

### Electric potential, voltage (article) ^{[4]}

Formal definition of electric potential and voltage. Coulomb’s Law lets us compute forces between static charges

Electric force and electric field are vector quantities (they have magnitude and direction). Electric potential turns out to be a scalar quantity (magnitude only), a nice simplification.

Begin with two positive point charges, separated by some distance . In this discussion, will stay fixed in place, and (our test charge) will move around.

### 7.2 Electric Potential and Potential Difference – University Physics Volume 2 ^{[5]}

– Define electric potential, voltage, and potential difference. – Calculate electric potential and potential difference from potential energy and electric field

Recall that earlier we defined electric field to be a quantity independent of the test charge in a given system, which would nonetheless allow us to calculate the force that would result on an arbitrary test charge. (The default assumption in the absence of other information is that the test charge is positive.) We briefly defined a field for gravity, but gravity is always attractive, whereas the electric force can be either attractive or repulsive

Calculating the work directly may be difficult, since and the direction and magnitude of can be complex for multiple charges, for odd-shaped objects, and along arbitrary paths. But we do know that because , the work, and hence is proportional to the test charge q

### Electricity – Calculating, Value, Field ^{[8]}

In the example, the charge Q1 is in the electric field produced by the charge Q2. This field has the valuein newtons per coulomb (N/C)

This equation can be used to define the electric field of a point charge. The electric field E produced by charge Q2 is a vector

Using equations (2) and , the field produced by Q2 at the position of Q1 isin newtons per coulomb.. When there are several charges present, the force on a given charge Q1 may be simply calculated as the sum of the individual forces due to the other charges Q2, Q3,…, etc., until all the charges are included
