The Pain of Electricity (AC versus DC)

Hi. One of the common questions is that: what kind of electricity hurts more? AC (alternating current) or DC (direct current)? So, I’m going to measure the electricity pain level on a human’s body, which is myself. But first, let’s measure the resistance of the skin on tongue and fingers for reference. So first, let’s […]

Electronics Tutorial #1 – Electricity – Voltage, Current, Power, AC and DC

hello everyone and welcome to this tutorial we’re going to start getting to the basics of electronics now for this first video what we’re going to do gonna and have try and have a basic understanding of electricity and how electricity works and the basic components of electricity now i’m going to start off with […]

Basic Electricity – Power and watts

Today I’m going to talk about watts and electrical power. In my previous video about voltage, I talked about how amperes is the number of coulombs flowing per second, and volts is the number of joules of energy transferred for each coulomb of charge that flows. I had an example set up where I had […]

Generate Electricity with Peltier Module – The Seebeck Effect

Hi Gang! I’m going to show how I used this Peltier module, and some cold and hot water to generate electricity. Here this LED is being brightly lit by it. I found my Peltier module in this hot and cold water dispenser. I opened up the back, removed the fan, and the heat sink. Stuck […]

Should a Person Touch 200,000 Volts? A Van de Graaff generator experiment!

Frostbite Theater presents… Cold Cuts! No baloney! Just science! Now, what’ll happen if a person were to touch it? Or, maybe a better question is, “Should a person touch it?” [Audience] Yes! Well, maybe yes, maybe no. Do you guys know what voltage is? What does voltage measure? It’s actually a measurement of energy per […]

How ELECTRICITY works – working principle

hey there guys Paul here from the engineering mindset dot com in this video we are going to be looking at how electricity works now this is pretty essential knowledge for any engineer so we’ll run through the basic parts of what you need to know so let’s start at the very basics and for […]

How to repair a 12 volt car battery using food grade Alum and baking soda for under 5 dollars

All right, I’m going to be trying to do today is convert Some of these old batteries that don’t hold charge anymore like this one this one has Not even a volt no oh two volts there Well over 2 volts 30 so basically nothing Screwdriver for this, but I just grabbed this because it […]

How to Make a Battery Protection Circuit (over-discharge protection)

Powering homemade projects with rechargeable batteries is actually more difficult than it sounds. This is because most battery types cannot be over-discharged, as doing so may damage the battery and make it unstable. Consumer electronics overcome this issue by using clever battery protection circuitry that constantly monitors the battery’s voltage, automatically switching the device off […]

Remove Complexity With EZ-Set Technology

Setting parameters on welding equipment is a challenge today, because we have welders of different skill levels and a lot of advanced features that makes it a lot harder to set equipment up. EZ-Set on the new Deltweld helps with that, because if you don’t know where to set your wire feed speed or your […]

How does a Transformer work ?

Transformers are capable of receiving AC power at one voltage and delivering it at another voltage. In this way they help achieve better transmission efficiency, while transferring the power over longer distances. In this video we will go through the working and construction of a three-phase transformer, by starting from its simplest form. The basic […]
