Would it be right to say that “Electric Potential” = the potential energy of an individual unit of charge at a certain point in a electric field?
Any replies from people who actually understand the topic (better than me, to say the least lol) and are able to clarify the topic (unlike my teacher), are highly appreciated and encouraged.

Electric Potential and Potential Energy
Electric Potential definition is as follows:
Electric potential (also called the electric field potential,
potential drop, the electrostatic potential) is defined as the amount
of work energy needed ...

How to use the equations for electrostatic work?
I was reading Griffith's Introduction to Electrodynamics (3rd ed.) when I stumbled upon two equations. In electrostatics, the work required to move a charge $q$ between two points with different ...

Confusion concerning notion and origin of electrostatic potential
An elementary circulation is mathematically defined by: $dC$=$\overrightarrow{OM}$.$\overrightarrow{X}$.
Now, we aplly this to a ponctual charge: $dC$=$\overrightarrow{OM}$.$\overrightarrow{E}$
And we ...

I am confused on how to think about potential energy stored in capacitors [duplicate]
Energy stored in capacitors is represented by
$$U = \frac{1}{2} QV$$
Now I have heard 2 reasons why there’s a half factor, unlike the general potential energy equation, which is $U = QV$.
Capacitors ...

Potential difference in parallel plate capacitors
I calculated the potential gain/difference for these two cases.
And found that, voltage difference would be higher for the parallel plate capacitor (2nd one). So from my understanding, the capacitor ...

Help interpreting equipotential line diagram
I immediately understood that this question is about how work done to get a test charge from one equipotential line to another doesn’t depend on the path taken but this diagram seems a little strange ...

What is the formula of potential difference and electric potential?
Electric Potential
Question 1. Is $V=W/Q$ or $V=P.E./Q$.
P.E. is electric potential energy
Potential difference
Question 2. Is $\Delta$$V=W/Q$ or $\Delta$$V=$$\Delta$$P.E./Q$.
Question 3. Is there any ...

Why is the potential not infinite?
One way to calculate potential (using infinity as our reference point) is to sum all the contributions of charges that are around.
Let's say I want to calculate the potential at some point on charged ...

Change in potential / potential energy of a charge in electric field [closed]
A uniform electric field of 2000 $(\frac V m)$ exists through all space (the field is in $+x$ direction). An electron is moved from the origin to the location where $x = -2.00 (m)$ and $y = +3.00 (m)$....

Electric Field Strength vs Electric Potential
This is the simple thing I’m confused about.
As I understand it, the electrostatic force from a charge out to a certain distance is inversely proportional to the distance squared (and electric field ...
