Hey i need help with general things with Electrician stuff.

Hi guys,

Im just wondering how i can get better at ohms law, any kind of suggestions on how i can get better at it?

I find it hard to grasp, and if you guys have any good videos or articles (or explanations yourselves) that would be much appreciated.

Thanks!

ohms law is a simple relationship between 3 variables. if you know 2, you can calculate the third. just transpose when necessary. e.g a 240V supply applied to a 20 ohm resistor. V =IR, so I = V/R = 240/20 =12A

I was always taught to look at the triangle ( like how you work out speed d=s/t)

W V
I V = watt is vera= I R = vera is randy

just look at it like a triangle, whichever your trying to work out put your finger over the letter and whatever is left is the equation. If you want to find out watts use the first one, and its I x V etc...

The way I was taught to remember ohms law was a triange.
v
----
I x R
Just cover the value you want and you get the calculation required.
