Electricity is the physical flow of electrons, referred to as an electrical current.
What is voltage? – Electricity Explained (3)
Briefly; Voltage is how we describe the strength of the current. The electric potential of a power source (such as a battery).
How much electricity does it take to power the world?
All around the world, millions of people are flipping a switch, plugging in, and pressing an ‘on’ button every second. So how much electricity does humanity use? And how much will we need in the future? Discover how much energy it takes to power the world, and how clean energy sources could help revolutionize our electricity supply.
VOLTS, AMPS and WATTS explained – Simple explanation for off-grid campers.
In this second episode of my “Off-Grid” mini-series I explain the basic electrical theory of voltage, current and power with some fun visual examples. This is aimed at people camping in caravans and motorhomes without access to mains electric supply but the video explains standard basic electrical theory so feel free to watch if you are just trying to understand the relationship between voltage, current and power.
Transistors Explained – How transistors work
Transistors how do transistors work. In this video we learn how transistors work, the different types of transistors, electronic circuit basics, how to build a transistor circuit, transistor amplifier, current gain beta, npn, pnp, heat sink, electronics and electrical engineering.
Electrical Basics: Volts, Amps and Watts explained using water analogy
Demonstration on how current flows and how volts, amps and watts relate to each other in electricity.
Amps, volts, watts explained…SEE what it really is all about.
Watch a dramatic and fascinating two minute documentary of the interrelationship between volts, watts, and amperage as Sunfacts skillfully demonstrates in his lab.
Do Different Voltages Mean the Same Thing?
Just as with the plethora of different materials in the electrical industry, have you ever wondered why we have so many voltages that can mean the same thing? It can be confusing at best! In the latest episode of Electrician U, Dustin answers this question to bring some clarity to the subject.
Ground Neutral and Hot wires explained
Ground neutral and hot wires explained. In this video we look at the difference and purpose of the ground wire, the hot wire and the neutral wire in a north american residential electrical system. We look at ground faults, GFCI, current, voltage and simple examples for each.
Veritasium’s Big Misconception About Electricity video and the point about Poynting
We discuss Veritasium’s video “The Big Misconception About Electricity”. In the video, Veritasium asks the question of when the light bulb in an extremely long circuit will actually light. This point is well discussed already in several videos, see this one in particular for a good explanation of the quiz.
