Moving on to our unit on the Physics of Electricity, it's time to talk about charge. What is charge? Is there a positive and negative charge? What do those things mean? In this episode, Shini talks about electrostatic forces, electrical charge, Coulomb's law, and the force between charged particles.

Introduction to electricity, circuits, current, and resistance. Created by Sal Khan. Watch the next lesson: https://www.khanacademy.org/science/physics/circuits-topic/circuits-resistance/v/circuits-part-2?utm_source=YT&utm_medium=Desc&utm_campaign=physics Missed the previous lesson? https://www.khanacademy.org/science/physics/electric-charge-electric-force-and-voltage/electric-potential-voltage/v/electric-potential-at-a-point-in-space?utm_source=YT&utm_medium=Desc&utm_campaign=physics Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need...

Huge thanks to the Royal Institution, Professor Frank James, and Katie Atmore for filming. For the Sixty Symbols version of this experiment click http://bit.ly/RGfLY5 Michael Faraday created the first electric generator in 1831 using a coil of wire and a permanent magnet. When the magnet was moved relative to the coil, current was induced in the coil. A similar experiment can be performed with a copper tube and a magnet. Although copper is not magnetic, it is a conductor. As the magnet falls through the pipe, the magnetic field changes over different sections of the pipe. This induces swirling currents (called eddy currents), which create a magetic field that opposes the motion of the magnet. This means work must be done to move the magnet through the pipe. This work generates the electri...
Voltage, Current, and Resistance - three of the most important electrical properties, are elegantly intertwined by way of a the simple equation - V = IR, better known as Ohm's Law.

We all know the words around electricity, "charge," "positive," "battery", and more. But where do they come from and what do they really mean? Let the history of these words illuminate the physics of electric phenomena. Lesson by James Sheils, animation by TED-Ed. View the full lesson: http://ed.ted.com/lessons/electric-vocabulary
Mr. Andersen contrasts series and parallel electrical circuits. A simulation is used to visualize electron flow through both circuit types.

Here, I'll introduce how resistance is an electrical friction, in that it takes useful energy and converts it to heat. Resistivity is related to conductance and conductivity, too. See how judgmental I can be?
Looking at the basic principles of electricity: current, voltage, resistance, power, KIrchhoff's rules
This is a short tutorial on the basics of Ohm's law. I hope it is helpful!
When we add in the concept of free charge, and then apply Gauss's Law, we uncover a new vector, D, that represents a useful quantity, the electric displacement. This makes solving certain classes of problems rather easy, skipping the part where we have to calculate the bound charge within a dielectric.
