The following topics are discussed: Electric Potential Energy, Electric Potential Difference, Electromotive Force, emf, Terminal Voltage, Basic Circuits, Current Direction, open, closed, and short circuits, electrical load, and light...

The work to move a charge through a uniform electric field is determined. An electron volt is defined.

This video shows how to prove that the electric field outside a uniformly charged sphere is the same as if the charged sphere were a point particle. Using Gauss' law, the electric field is shown to be constant and dependent only on the...

AP Physics C: Electricity and Magnetism review of Current, Resistance, and Simple Circuits including: deriving electric current in terms of drift velocity, current density version of Ohm’s law, defining resistivity, deriving resistance,...

Press conference announcing the first direct detection of gravitational waves -- February 11, 2016

Dear Calculus 2 Students, This is why you're learning Taylor Series

NASA is about to launch a new spacecraft to look at the universe in X-ray light. The Imaging X-Ray Polarimetry Explorer, IXPE, will look at extreme objects such as black holes, neutron stars, and supernovae, asking fundamental questions...

This video provides an overview of non-contact forces, such as gravitational, electric, and magnetic forces, explaining how they act at a distance without physical contact between objects. It covers the concepts of force magnitude,...

In this video, we learn about electric fields and the electric force between charged objects. We see how a charged comb can create an electric field that attracts nearby pieces of paper. This video is part of the 9-part series, Electricity.

Water. It's an essential building block of life, constantly moving in a hydrologic cycle that flows in a continuous loop above, across and even below the Earth's surface. But water is also constantly moving through another cycle --...

Do cell phones placed in a microwave still receive signals? What is the difference between microwave oven radiation and the signals used by your phone?

The video explains how objects can become charged by the transfer of electrons, resulting in static electricity. It also discusses how charged objects exert non-contact forces on each other, with like charges repelling and opposite...

This nugget explains the features and mathematical expressions of Bohr's model and its advantages over Rutherford's model.

Electric Field Due to a Ring of Charge

As always, the steps of DNA electrophoresis depend on your specific lab and protocol. Here, we look at the general theory of separating DNA on an agarose gel by electrophoresis and what it is used for in the lab. We will also learn about...

Electric Field of Variably-Charged Rod

What is alpha radiation? How does it happen? And what does it leave behind? Find out all the answers in this GCSE / K12 Physics video from The Fuse School



At Fuse School, teachers and animators come together to make fun &...

Polarizability (Part 1/2)

The History of Physics (Part 2)

We've covered Gauss' Law for the Electric Field, but what about the magnetic field? That's covered in the second of Maxwell's equations, which we'll discuss in this video. Gauss' Law for the Magnetic Field displays the simplest facts...

In this video, we explore the fascinating phenomenon of St Elmo's Fire, a glowing plasma that occurs during storms. We learn about its origins, which are rooted in the brave actions of a Christian saint, and delve into the science behind...
