# Lessons on Electrostatics

Name  Description  Type
Intro to Electrostatics A nice introduction to the study static electricity. Animation & Explanation
(HTML5)
Charging an Object Using Friction This lesson examines some common situations of charging an object rubbing it against a different object. Animations & Explanation
Insulators & Conductors This lesson addresses the differences between insulators and conductors.   Animations & Explanation
Electrostatics Lab Activities This lesson illustrates what is actually happening in common electrostatics lab experiences.  It is recommended that you use this lesson either during or after going through the electrostatics lab. Lesson & Animations
Losing Charge This lesson illustrates how water vapor and other particles in the air can steal charge from a charged object. Animation & Explanation
Electrostatic Force - Coulomb's Law This introduces the concept of electrostatic force and how to calculate it.  It also addresses the concept of quantity of charge. Explanation
Electric Field Strength This lesson introduces the concept of an electric field and the calculation of field strength or field intensity. Animation & Explanation
Electrostatic Field Mapping This demonstrates the idea behind mapping an electric field. The field is created between two fixed particles.

Animation & Explanation
Electrostatic Field Mapping Applet
NEW
This applet lets you move two charges around and see the resulting electric field diagram and field lines. Interactive Java Applet
Electrostatic Field Mapping Applet #2
NEW
This applet lets you place various charges, and automatically draws both electric field lines and equipotential lines. Interactive Java Applet
Electrostatic Force and Fields This is a great dialogue and interactive segments to teach the concept of an electrostatic force and electric fields.
CAUTION: This site demonstrates a field using a negative test charge.  Remind yourself continually that an electric field is defined in terms of a positive test charge.
Interactive Dialogue (Java)
Electrical Energy and Electrical Potential This lesson focuses on the concept of electrical potential, or potential difference, or voltage, or electromotive force.  This is perhaps the most difficult concept in electricity only because we have so many words to describe the same thing. Lesson & Animations
Equipotential Lines This lesson illustrates the concept of equipotential lines and electrical potential difference. Lesson & Animations
Charged Parallel Plates This lesson demonstrates several properties of oppositely charged parallel plates. Lesson & Animations
The Millikan Oil Drop Experiment An online version of the classic experiment used by Robert Millikan to determine the charge on the electron. Simulation
(HTML5)
Van de Graaff Generator This lessons describes how a Van de Graaff generator is able to create huge electrostatic charges.  Animation & Explanation
The Proton Gun Lab This interactive lab allows you to place charges near the path of a proton being fired out of a proton gun. Created by Raman Pfaff. Interactive Lab
(Shockwave)
Moving Charge in an Electric Field
NEW
This interactive lab allows you to adjust initial velocity, electric field strength, charge and mass and track the effects on the charge's motion. Interactive Lab
(Java Applet)
Forces on Multiple Charges This demonstrates what the forces of attraction or repulsion look like between three spherical charges.  Movie & Explanation
Lightning The electrostatic process of lightning is addressed here.  Animation & Explanation
Electricity Review A collection of multiple choice questions providing immediate feedback. Multiple Choice Practice
