Ohms Law Explained - The basics circuit theory

Ohms Law Explained. In this video we take a look at Ohms law to understand how it works and how to use it. We look at voltage, current, resistance and the relationship between these. We also use ohms triangle to solve examples.

I became an electrical engineer 40 years ago. If you wanted to learn the things covered in this series you had to go to college... or spend a boat-load of time at the library. Those who grew up on KZbin have no idea how fortunate they are that stuff like this is at their fingertips. Your videos are tremendous, as well as an outstanding foundation for anyone going into the engineering field.

KZbin is awesome, as a gen z I do appreciate it. Years of knowledge and experience at your fingertips and the only person you have to ask is a computer. There's no need to spend years of your life and hard earned money studying something you might become uninterested in, youtube lets you learn an infinite amount of things for free and you wont be under the pressure of a money investment. I think it makes society better even, as easy access to learning gives people the freedom to educate themselves despite limitations they may have. For example, limited money, different learning style, different optimal learning conditions, and the limitation that applies to everyone, time. I choose to spend my time on earth learning. If learning and growth rise above hate and ignorance, we will live in a more beautiful world.

Now I can't wait to go watch your other videos and finally understand what they're saying when they talk about their latest projects :)

Sometimes science is just turtles all the way down: 'Why do engineers use (j) = sqrt(-1) instead of (i)?' 'Because 'i' was already taken.' 'What is 'i' used for?' 'Current.' 'Why do we use 'i' for current? Why not 'C'?' 'Because 'C' was already taken...'

reminds me of why the local drive in your computer that has its operating system installed on said drive, is called the "c" drive, because "a" and "b" were taken, both a and b were used for floppy drives.
