A discussion of electrical current, and how to understand it.

A pencil lead and some batteries make a small plasma cutter that we use to etch a pattern in aluminium foil. Parts Needed: 4 9V battery, 2 clip leads, 1 5mm pencil lead, aluminum foil, box or tub, rubber band

In this video, we delve into the world of ideation and innovation, exploring the differences between these two often interchanged terms. Join us as we break down the cognitive process of ideation, where individuals or groups generate new...

This video explains the motor effect, which occurs when a current-carrying conductor is placed in a magnetic field, creating a force between the conductor and the magnet. The video discusses how to calculate the magnitude and direction...

On this episode, Mark is getting shocked... by an Electric Eel! Yep, you read that correctly.. he's sticking his hand in a tank to experience the full force of the shock of an electric eel - so, how badly will it hurt, and will he be...

This is a lecture video on the differences between direct and alternating potential difference. The video defines and explains the two types of current and provides examples of each. It also includes graphs that demonstrate how potential...

This nugget explains Ampere's Circuital law and its mathematical expressions to illustrate the relationship between electric current and magnetic field

This nugget explains the formation and behaviour of magnetic field lines. It also explains mathematical parameters of a bar magnet and a solenoid.

Batteries store chemical energy that can be converted into electricity, providing a source of power. By connecting a battery to a circuit, a chemical reaction takes place, causing a buildup of electrons at the anode and creating an...

"Uses of Nuclear Radiation What have the Hulk and Spiderman got in common? They both gained their super powers because of radiation. Well, in films and comics at least. In real life, radiation has never given anyone super powers. But...

Learn the basics about electroplating. The anode is positively charged, and the cathode is negatively charged. They are immersed in a solution called an electrolyte. The electrolyte and the anode are selected based upon the material that...

This video explains the basics of electric circuits, including the differences between series and parallel circuits, how to measure potential difference and current, and the dangers of short circuits. The simulation used in the video...

Zeina is Managing Director at The Carlyle Group advising on Corporate Private Equity and European buyout opportunities. Prior to joining Carlyle, Zeina was an Associate at European Digital Capital, a technology venture capital fund....

The video is a lecture presentation on the use of orders of magnitude in physics. It defines orders of magnitude as comparing numbers or values in terms of powers of 10 and explains how to use decimal prefixes for expressing very small...

How Electric Motor Works - 3 phase induction motor AC alternating current.

The video is a lecture presentation on electrical energy transfers. The presenter discusses three equations for power and how they can be combined to calculate the energy transfer by an electrical device in a given time. The symbols and...

Sometimes physics and nature go hand in hand. In this video we’re going to look at using Fleming’s left hand rule to help us remember how current, magnetic fields and direction go together.

In this video, Marcus and the speaker discuss the concept of the SILO effect within their office and introduce "Blue Moon Day" as a way to encourage teamwork and creativity. They address the challenges of working in silos and emphasize...

An introduction to Ohm's Law and the basic math needed to understand it.

Inductors Explained, in this tutorial we look at how inductors work, where inductors are used, why inductors are used, the different types. We take an in depth look at how the circuits perform with a parallel resistive and inductive load...

Electromagnets are incredibly useful. They can do all the things a normal magnet can do, but can also be switched on and off. Electromagnets have many uses, from moving cars in a scrap yard to high speed Maglev trains. The trains are...

A discussion of resistance, and how to understand it.

Transformers change the potential difference of electricity. There are two main types of transformer that are used in the national grid. These are step up and step down transformers. Each of them consists of a two coils of wires around...
