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 […]

Difference between AC and DC Current Explained | AddOhms #5

If you’re looking for a video on legendary rock music you might have found the wrong channel. On a previous Add Ohms video we looked at Voltage, Power, and Current… …and you might remember this animation. one problem with this animation is that the voltage source shown was an AC source while the current flow […]

The Scariac (Poor Mans Variable Power Controller)

Mixing water with electricity is typically discouraged, and for good reason, but in this project we’re pumping electricity into water, and a bit of drain cleaner to create a poor mans power controller. You might have heard of a Variac. This is the Scariac. In a couple of other projects, we fashioned a homemade stick […]

What is a Transformer? An Electrical Transformer Tutorial

In this video I am going to explain how transformers work and show you how to wire one up to step mains voltages down to lower voltages that your projects may need. In my project we will step down 120V to 24V but the same principles will apply to most transformers. I’ll also give you […]

Diode Tutorial & How to build an AC to DC power supply

In this tutorial, I’m going to cover silicon diodes, bridge rectifiers, and how you convert AC to DC. Here’s the schematic symbol of a diode and a picture of the real thing. The little stripe on the end of the diode tells you which way to put it in your circuit But what is a […]
