E=IR is a poor choice of variables for the average person, especially since Ohm's Law is not a math problem - it's a physical concept. There are no Es, Is or Rs on a meter, and having to learn one set of variables for math and another for reading manuals has never made sense to me. Also, using the formula that has volts isolated makes it harder to understand the concept. Volts and Ohms make Amps - so V/Ω=A is better. If they have to do fractions anyway, students should start with this one.
Water is a poor choice -- fluids are incompressible, yet we refer to voltage as pressure. A better example is air pressure. Most people have never had any training in fluids or hydraulics, but nearly everyone has put air in their tire or worked with a can of spray paint.
Thank you for posting this. I was having trouble understanding how electricity worked and what the definitions of related terms were, but your video cleared everything up for me. Nice diagrams too.
WTF are watts?

And if there was no resistance?

@MrGeneralRelativity he just said it would cause spark or explosion because a short circuit has formed.

Nice video, I use a slightly different analogy, but water is a good euphemism

Is this, or can you make this program available for the public :D
Or link to it if it's already available :D
