# Simple Electric Potential/Field problem

• Defennder
In summary, an electric potential/field problem involves calculating the electric potential or electric field at a specific point in space due to one or more charged particles. Electric potential is a scalar quantity that describes the potential energy of a charged particle at a certain point in space, while electric field is a vector quantity that describes the force experienced by a charged particle at a certain point in space. The electric potential at a point can be calculated using the equation V = kQ/r, where V is the electric potential, k is the Coulomb's constant, Q is the charge of the particle creating the potential, and r is the distance from the particle to the point. The electric potential/field at a point is affected by the magnitude and location of the

## Homework Statement

Okay this is a simple first year physics question, but I couldn't find anything about it online. Using the simple equation for electric field/potential due to a point charge, what's the electric potential/field at the coordinates of the point charge itself?

## The Attempt at a Solution

I'm tempted take limits as r approaches 0, but that seems to imply it approaches infinity which appears absurd. Either that or it's undefined. Anyone?

## What is an electric potential/field problem?

An electric potential/field problem involves calculating the electric potential or electric field at a specific point in space due to one or more charged particles.

## What is the difference between electric potential and electric field?

Electric potential is a scalar quantity that describes the potential energy of a charged particle at a certain point in space, while electric field is a vector quantity that describes the force experienced by a charged particle at a certain point in space.

## How do you calculate the electric potential at a point?

The electric potential at a point can be calculated using the equation V = kQ/r, where V is the electric potential, k is the Coulomb's constant, Q is the charge of the particle creating the potential, and r is the distance from the particle to the point.

## What factors affect the electric potential/field at a point?

The electric potential/field at a point is affected by the magnitude and location of the charged particles creating the potential/field, as well as the distance between the charged particles and the point in question.

## How can I use electric potential/field to solve real-world problems?

Electric potential/field can be used to study and understand the behavior of charged particles in various systems, such as electronic circuits, electric motors, and power lines. It can also be used to design and optimize devices that use electric fields, such as particle accelerators and mass spectrometers.
