Electric Fields In this lesson, Chad provides a lesson Electric Fields. The lesson begins with the mathematical relationship between the electrostatic force and the electric field: F=qE. This is used to derive a simple expression for the electric field and to show that the SI unit is the N/C. The electric field due to a point charge is then presented: E=kq/r^2 and is used to show the relationship to Coulomb's law. Electric Field Lines Chad then shows how to draw electric field lines, explaining the rules for drawing electric field lines. He demonstrates that generally, electric field lines originate on positive charges and terminate on negative charges and give the direction of the electric field at that point in space. He also demonstrates how the number of electric field lines is related to the strength of the electric field and the magnitude of the charges in the diagram. Electric Fields Problems The lesson concludes with the solving of a couple physics electric fields practice problems. The first involves solving for the force and acceleration of a charged particle in an electric field. The second involves solving for the location in space of where the electric field is zero with nearby point charges. 00:00 Lesson Introduction 00:50 F=qE; Introduction to Electric Fields 08:09 Electric Field Lines 10:51 Electric Field, Charge, and Acceleration Calculation 12:28 How to Calculate where the Electric Field is Zero Check out Chad's General Physics Master Course: https://www.chadsprep.com/physics-youtube #generalphysics #physicstutorial
