Electric field strength = - potential gradient. Let's use this to calculate potential differences in uniform electric fields. Created by Mahesh Shenoy.

Let's use Gauss law to calculate the electric field due to an infinite line of charge, without integrals. Created by Mahesh Shenoy.

Now we can equate both sides of Gauss's law & calculate the electric field strength inside the shell.

The electric field is defined as the force experienced by a unit charge (1C) placed at the a location in space near the constellation of given charges. The 1C unit charge is called the "test charge".

Let's calculate the electric field vector by calculating the negative potential gradient. We first calculate individually calculate the x,y,z component of the field by partially differentiating the …

Learn about the formula used to find the magnitude and direction of the electric field between two point charges, and see two examples of how to calculate the magnitude of an electric field.

Formal definition of electric potential and voltage. Coulomb's Law lets us compute forces between static charges. Now we explore what happens if charges move around. We find out what it …

In this video David solves an example 2D electric field problem to find the net electric field at a point above two charges.

Let's explore how the strength of electric & magnetic fields affect the energy at which the particles exit the cyclotron. Spoilers - The effects are counter intuitive!
