Liquid metal batteries are being hailed by some as the most transformative and revolutionary energy storage technology since John B. Goodenough came up with lithium ion batteries several decades ago. But the road from laboratory to full scale production has been a long and winding one, and commercial success is still by no means guaranteed. So, will liquid metal batteries change the world?
Voltage Explained – What is Voltage? Basic electricity potential difference
What is voltage and what does it do? In this video we discuss how it work and its purpose to understand how electricity works. We’ll look at voltage for both alternating current and direct current starting off very simply and slowing building up as we go along to build your base knowledge including how to measure voltage with a multimeter.
What is an Amp? – Electricity Explained
When you have an electric current it’s useful to be able to measure that current. This is done in amps (often using a multimeter). This video explains what an amp (A) (short for ampere) is, which also involves the coulomb (C). The coulomb is the SI standard unit for electric charge, whereas the amp is the SI standard unit for current.
1A equals 1C per 1s (seconds).
One coulomb is roughly equivalent to 6.24 quintillion(!) electrons carrying a charge. That’s at 1A. Imagine how many electrons pass a certain point when the current is 5000A(!)
What is electricity? – Electricity Explained
What is electricity? How does electricity work? What do electrons do? What is short circuiting? These are all questions answered in this video: A fundamental explainer on what electricity is and how it works.
In following videos we’ll look at voltage, ampere, ohm (resistance) and many more electricity related topics. All of this is to build a foundation of knowledge to serve all the future (and past) videos here on Into The Ordinary.
A couple of choices were made during the production of this video, that can be helpful to know:
- I chose to mention the Bohr-model in relation to the orbital model to bring the point across that there is more to atoms than just this. The What Are Atoms? video better explains orbitals than this video does, though.
- I intentionally used the word “shells” instead of orbits because it better catches what electrons are in real life, although still a simplification. This video is about electricity, not particle physics.
- Power generation, how batteries work, amps, volts, ohms, are all topics I want to address in separate videos.
- There will probably be a few more questions about this video, which I will try to address in the comments or in the description, here.
Never directly connect a wire to both holes of a wall socket, and never directly connect a wire to both ends of a battery! This can be dangerous and potentially life-threatening!
Introduction To Electric Charge
A simple and easy introduction to electricity. It covers electric charge, the discovery of electricity, the nature of electricity and some of the more technical stuff for the classroom for you students.
The quest for Nikola Tesla’s wireless power technology
Nikola Tesla’s biggest dream was a worldwide network of wireless power transmission. He built a lab and a massive prototype transmission tower…that never worked. But, a century later, engineers are chasing the same dreams of wireless power and making some tantalizing headway.
How it Works: Electricity
The fundamental scientific properties are explained.
How ELECTRICITY works – working principle
In this video we learn how electricity works starting from the basics of the free electron in the atom, through conductors, voltage, current, resistors, led, to capacitors and transformers.
How Batteries Work – Battery electricity working principle
How does a battery work, learn from the basics where we use and battery and how batteries work.
