# Introduction to Electrostatics (Electric Force and Field)

Study the relationship between stationary charged objects

HOW THIS COURSE WORK:

What you’ll learn

• Understand the forces between charged objects (Coulomb’s Law).
• Identify the differences between insulators and conductors.
• Understand how to polarize an insulator and a conductor.
• Find the net electric field from point charges and charged bodies.
• Study the motion of a charge in a uniform electric field.
• Find the electric field using Gauss’s Law and symmetry.

Requirements

HOW THIS COURSE WORK:

This course, Introduction to Electrostatics (Electric Force and Field), includes the first three sections you will learn in Electricity & Magnetism, including video, notes from whiteboard during lectures, and practice problems (with solutions!). I also show every single step in examples and proofs. The course is organized into the following topics:

• Electric charge
• Insulators vs. Conductors
• Coulomb’s Law
• Polarization
• Electric field from point charges
• Superposition of electric fields
• Electric field for charged bodies
• Electric flux
• Gauss’s Law (Symmetry)
• Conductors in Electrostatic Equilibrium

CONTENT YOU WILL GET INSIDE EACH SECTION:

Videos: I start each topic by introducing and explaining the concept. I share all my solving-problem techniques using examples. I show a variety of math issue you may encounter in class and make sure you can solve any problem by yourself.

Notes: In each section, you will find my notes as downloadable resource that I wrote during lectures. So you can review the notes even when you don’t have internet access (but I encourage you to take your own notes while taking the course!).

Assignments: After you watch me doing some examples, now it’s your turn to solve the problems! Be honest and do the practice problems before you check the solutions! If you pass, great! If not, you can review the videos and notes again.

THINGS THAT ARE INCLUDED IN THE COURSE:

HIGHLIGHTS:

#1: Downloadable lectures so you can watch the videos whenever and wherever you are.

#2: Downloadable lecture notes so you can review the lectures without having a device to watch/listen.

#3: One problem set at the end of each section (with solutions!) for you to do more practice.
