In the previous episode we discussed what happens when we use electrophilic aromatic substitution to add a group to a benzene ring, but what happens when you try to add even more groups? Well, things get a little more complicated. In...

In this video Paul Andersen explains how all objects contain positive and negative charge. Neutral objects contain an equal amount of positive and negative charges. Charged objects have more positive or negative charges. Like charges...

As we learn more about electricity, we have to talk about fields. Electric fields may seem complicated, but they're really fascinating and a crucial part of physics. In this episode of Crash Course Physics, Shini chats about capacitors,...

In this video Paul Andersen introduces electric charge. Electric charge has been studies by humans and was generalized by scientists such as Benjamin Franklin. The amount of charge in a system is conserved but individual charges can move...

In this video Paul Andersen explains how vector addition can be used to determine the electric field of a dipole.

In this video Paul Andersen explains how we can use Coulomb's law to predict the structure of atoms. These predictions can be verified through the use of Photoelectron Spectroscopy (PES). Electron's are help around the nucleus because...

In this video Paul Andersen explains how the conservation of charge applies to objects in a system. When a charged object induces charge or conducts charge to a neutral object the net total of charge will not change. Grounding allows...

In this video Paul Andersen explains how electric charge is quantized and how the smallest unit of charge is 1.6x10^-19 C, or the elementary charge. Robert Millikan discovered the elementary charge using the oil drop experiment. ...

In this video Paul Andersen explains how the electric field strength is directly related to the amount of charge that generates the field.

Lake Maracaibo is the stormiest place on the planet. Thunderstorms rage above this massive body of water for up to 200 days of the year, with each ear-splitting event lasting for several hours. But why? Graeme Anderson lists the factors...

In this video Paul Andersen explains how a vector field shows the distribution of vector quantities. In AP Physics 1 student should be able to map and understand gravitational vector fields. In AP Physics 2 students should be able to...

Today we’re looking at silicon, and how introducing small amounts of other elements allow silicon layers to conduct currents, turning them into semiconductors. We’ll explore how putting two different types – N and P semiconductors –...

In this video Paul Andersen explains how current moving through a wire will generate a magnetic field tangent to the wire. As the current increases the magnetic field will increase and as the radius from the wire increase the magnitude...

In this video Paul Andersen explains how at the smallest level all matter is made of fundamental particles; including quarks, electron, photons and neutrinos. He explains how understanding the properties of these particles allows us to...

You’re probably familiar with the basics of magnets already: They have a north pole and a south pole. Two of the same pole will repel each other, while opposites attract. Only certain materials, especially those that contain iron, can be...

In this video Paul Andersen explains how the charge distribution can be affected my electric forces produced by a charged object. In an insulator charges are fixed but in conductors the charges can move. Induction occurs when the...

A SciShow Kids viewer wants to know, 'Why do lightning and thunder happen?' Get your raincoat, because Jessi will take you inside a thunderstorm to give you the answer!

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...

Mr. Andersen shows you how to name covalent and ionic compounds.

New ReviewIt's like it's flying!

This video provides an overview of how having a criminal record can impact your job search. It explains the importance of understanding what information is included in a background check, how charges and convictions can affect your...
